7 The diary

There are two ways of getting into the diary:

To see the display of the current week:

You can see when you are free at a glance:

The four dashes under each date represent morning. lunchtime, afternoon and evening. If you have made an appointment during one of these time periods the dash is replaced by a solid block.

The cursor is a flashing arrow pointing to the current time, in this example lunchtime on Saturday 7.
Mo Tu We Th Fr Oct89
02 03 04 05 06 07 08
 =  =  =  =  = >=  =
 =  =  =  =  =  =  =
Morning - midnight to 12.00 noon.
Lunchtime - 12.00 noon to 2.00pm.
Afternoon - 2.00pm to 6.00pm.
Evening - 6.00pm to midnight - an appointment is set at some time during this period.

Note: If these four time slots don't suit your schedule, you can change their times in the diary Setup option.

Entering an appointment

To move the arrow to the slot you want:

You now see the page for the day you have chosen. If you haven't made any appointments it looks like this:
Sun  8 Oct 1989 Wk40

     <Free Day>

To make an appointment you type in the entry before you set the times.

As long as the start time you set has not passed, you are now asked whether you want an alarm:
Alarm? Y/N

If you press Y, you are asked how long before the start time you want the alarm to sound:
Alarm: 15 minutes

The page for the day now changes like this:
Sun  8 Oct 1989 Wk40
 6:00a <Free>
1:30p <Free>

he appointment is now set. A bell before it indicates an alarm. If the entry is too long to fit, it scrolls round.

In the screen above, the entry has been set to last from 12:00 to 1:30. Free slots are available above and below.

You could now return to. the week view with ON/CLEAR or you could press -->; to see the next day.

You can also make another entry. For example to make an appointment in the afternoon after your lunch date:

The day now looks something like this:
Sun  8 Oct 1989 Wk40
 1:30p <Free>
 3:00p TENNIS

Note: If you want to speed up the process of making an entry by suppressing the alarm prompts, you can do this in the diary menu option Setup.

Switching off ringing diary alarms

Diary alarms work just like ordinary Organiser alarms, but in addition. your diary entry is displayed like this:
Fri  7 Jul 1989 Wk27


Missed diary alarms

When you press ON/CLEAR to switch a ringing diary alarm off, this acknowledges that you have seen it. If you miss some diary alarms, you see a message like this the next time you switch on:
Review? Y/N

Changing or deleting a diary entry

To change an entry:

To delete an entry:

If the entry is not near the current date. the quickest way to get to it is to use the diary menu options Find or Goto.

The diary menu options

You can display the diary menu on the week view or the day view. To see all the options, look at the version of the menu available from the day view.

Press MODE and the diary menu appears. On a one-line menu like this one:

Find and Goto are short-cuts to entries and dates.
Copy, Cut and Paste copy and move entries.
Alarm sets or removes alarms.
Tidy deletes or files away out-of-date entries.
Print prints out the diary.
Save and Restore file away and restore whole diaries.
Xrestore restores a diary created on a Model CM or XP.
Setup allows you to tailor the diary slots to suit your schedule, and to suppress alarm prompts.


You find a diary entry using a search clue.

If it is not the one, press EXE again to see the next matching entry. When NO MORE ENTRIES is displayed, you can change the clue and search again.

When you have found the entry you were looking for:

You can now delete. edit or move the entry as you wish.

Note: A quick way of deleting unnecessary entries is to use DEL in Find. When you confirm with Y, the entry is deleted and you see the next matching entry.


This allows you to go straight to any date to make an entry or change one which is already there.

Cut Copy and Paste (day page only)

You can use these functions to move an entry or make multiple copies of it for regular appointments.

To move an entry:

To duplicate an entry:

Once you have cut or copied, you can go to empty days and free slots, press MODE again, select Paste and paste the entry into as many slots as you like:
Fri 11 Aug 1989 Wk32
12:30a <Free>
 8:30p SQUASH
 9:30p <Free>
<-- SQUASH -->
Mon  4 Sep 1989 Wk36
12:30a <Free>
 8:30p SQUASH
 9:30p <Free>

When you paste the entry in, its duration and alarm time are also copied. You move straight to the timesetting stage. When you've pasted it, the copied entry remains in memory and can be pasted into other slots until you replace it by cutting or copying something else.

Alarm (day page only)


You can stop the printing by pressing ON/CLEAR. If there is no printer attached, you get the error message DEVICE MISSING. See Chapter 17 for more details about printing.


Lets you tidy up the diary by deleting out-of-date entries. This can be useful to free memory space.

If you choose to save the entries, you are asked for the name of a file to put them in:
Save A:_

Filenames can be up to 8 characters long and must start with a letter.

If the file you named already exists, you are shown this message:
Append Delete

Select Append if you want to add the tidied entries to the existing file or Delete if you want to delete the existing file and replace it with a new file containing the tidied entries.

Save and restore - filing diaries

You may want to save your diary in a file on a Datapak at some time so that you can start afresh and free some memory. It is saved as a data file, so you should give it a name which will distinguish it from your other data files. You can restore all or part of it at any time.


This saves, all the entries in your diary in a file.

Filenames can be up to 8 characters long and must start with a letter.

If the file already exists, you are given this choice.
Append Delete

Select Append if you want to add the diary entries to the existing file, or Delete if you want to delete the existing file and replace it with the newly saved one.


If you have saved a diary in a file, you can restore all or part of it with this option.

You are asked for a diary file to restore:
Restore A:_

Press MODE if the diary file is on a pack, then type in the filename or just press EXE and you see a list of all the diary and data files. Choose the diary file you want by moving down with DOWN and pressing EXE on it.

(For more detailed information on selecting a file from a list, see the Files Chapter.)

Choose to restore all or part of the diary file.

Whichever you select, you then specify how the diary file is to combine with the current one:

There is more about diary files in the chapter on handling any type of file in the Programming Manual.


This restores a diary that was created and saved on an Organiser II model CM or XP. You are asked to specify the filename and you select it in the same way as in Restore.

However, you cannot merge a CM/XP diary with the current diary - it will just be overwritten.


This alters the way the diary is set up.

Slot 1 always starts at midnight (00:00a) and slot 4 always ends at 00:00p. However, you can change the three divisions in between.

This example: 1:00p 2:00p 7:00p would give the following slot times:
Slot 1   0.00a to 1.00p
Slot 2   1.00p to 2.00p
Slot 3   2.00p to 7.00p
Slot 4   7.00p to 0.00p

The fourth line of the screen gives you the chance to switch alarm prompts off.

If you do, the Alarm? Y/N prompt never appears but you can still set alarms using Alarm on the diary menu.

8 The calculator

This chapter shows you how to do a simple calculation and then how to use a result again, edit your calculation, and use the 10 memories.

It then goes on to explain how to use the calculator in conjunction with OPL functions and procedures.

Doing a calculation

In the calculator you don't need to use SHIFT to get numbers and symbols - they are on automatically. You use SHIFT to get letters.

The basic arithmetic operators, +,-,/ (divide), * (multiply) and ** (raise to a power) are used in the same way as they would be in a written calculation. Any number of levels of brackets may be used.

If you have typed something in wrong, you can edit the calculation, by using the arrow keys and DEL.

Clearing the calculator

Using a result again

You might decide to use the result from one calculation as part of another one. Do another calculation and when the result is displayed:

The old result is shown on the calculation line with the new number or symbol at the end:

Editing a calculation

A useful feature of this calculator is the ability to modify your original calculation. Do another calculation and when the result is displayed:

The result disappears and you can edit the calculation.

Alternative ways to edit the calculation

If you make an error such as typing 7-*5 which the calculator can't understand, you see this message:
  press SPACE key


Percentages are calculated like this:


To add VAT (a 15% purchase tax) to 345: 345+15%=396.75

To find out what the price was before VAT: 396.75>15%=345

To find out how much of a total price is VAT: 396.75<15%=51.75

Calculator memories

Built into the Organiser are ten memories which can be used either in the calculator or in OPL.

You can store numbers in them for use in calculations. You can then add to them, subtract from them and clear them.

In the calculator and OPL they are referred to by the same names, M0 to M9.

To store the result of a calculation to memory M0:

The name of the first memory, MO, appears on the left of the result, and above the calculation you are shown the current contents of it:
±             9:30a

To store the result in a different memory slot:

You can now modify the chosen memory in three ways:

EXE Stores this result in the memory, replacing the current contents. + Adds this result to the memory contents. - Subtracts this result from the memory contents.

Including numbers stored in memory in calculations

You can include the figure you stored in memory M0 in calculations, like this: 27*M0/2.

List functions

You can operate on lists of numbers using the following functions (from OPL) which find out:

SUM The sum.
MEAN The mean (average).
STD The standard deviation.
VAR The variance.
MAX The largest item in the list.
MIN The smallest item in the list.

The items in the list go in brackets straight after the function and are separated by commas. For example: MEAN(8,9,10)

Remember that you have to use SHIFT to type letters in the calculator.


You can use E as the exponent. For example, 3.6E4 represents 36000.

Decimal places

Do the calculation 4*7/9. Notice that the result 3.11111111111 is displayed with 11 decimal places. This is how the calculator normally works - allowing as many significant digits as will fit in a total of 12 figures. If you work with money, and want to fix the number of decimal places to 2:

Do the calculation 4*7/9 again. The result is 3.11 You can have from 0 to 12 decimal places. To return to normal type only FIX=

OPL and the calculator

OPL functions in calculations

In your calculations, you can use any of the numeric functions of the Organiser Programming Language even if you never use OPL otherwise. The numeric functions are listed at the beginning of Chapter 8 in the OPL manual. You can use them to do far more operations than are available on an ordinary calculator. For example: SIN(PI/4)/(3.8*COS(1.2))

Here the SIN, COS and PI functions are used.

Another example might be to find the sine of 30deg. This is typed in like this: SIN(RAD(30))

The RAD function converts from degrees to the radians which the SIN function requires.

When you press EXE, if there is an error in your calculation. you get an error message and should, as the message says, press SPACE and correct it. The cursor flashes on the, unrecognised character.

For instance, if you included a character which was not a function name or an arithmetic operator, like this, the cursor would be flashing on the P: 10*P/(22/7)

Your OPL procedures in calculations

If you have typed any OPL procedures into the Organiser, you can include the procedure names in your calculations. All procedure names end in a colon. Put the value you want to operate on in brackets after the procedure name. In this example the procedure name is TAX and the value is 20000: TAX:(20000)

The value you want the procedure to operate on is called a parameter. You can use a memory name as a parameter: TAX:(M1)

Procedure names can be included in quite complex calculations. For example, if you had a procedure called FACT: which worked out the factorial of a number passed to it, then you could include this in your calculation like this: 587*2.883/(4+FACT:(3))

The value 3 is being passed to the procedure. The returned value is then added to 4 and the rest of the calculation performed on the result.

From the calculator, parameters are passed as floating point numbers. To pass an integer to a procedure, you must use the INT function like this: 5/3+PROC:(INT(10))

The OPL manual shows you how to write your own OPL procedures, and there are examples in Chapter 7.

9 The notepads

Organiser notepads are the ideal place to keep lists of things to do. The notepad has its own calculator which makes notepads ideal for keeping track of expenses. They can also be password- protected and so are suitable for secret data such as cash card numbers.

This chapter shows you how to use the main notepad, then how to use the options on the notepad menu and how to create extra notepads.

Using the main notepad

Two things are different from typing in a record:

After you exit, everything you typed in will still be there the next time you enter the notepad and you can then add and delete things as you wish.

The notepad menu options

Press MODE when you are in the notepad to see the menu.
Find Save Load New->

On a one-line menu like this one:

The fifteen options are:
Find Finds a given search-clue in the notepad.
Save Saves a named notepad file.
Load Loads a different notepad file.
New Creates a new notepad.
Home Takes you to the start of the notepad.
End Takes you to the end of the notepad.
Calc Does calculations on numbers in the notes.
Sort Sorts the lines in the notepad alphabetically.
Number Numbers the lines in the notepad.
Password Provides password security.
Print Prints the notepad.
Dir Provides a directory list of all notepad files
Copy Copies a notepad file
Delete Deletes a notepad file
Zap Clears the current notepad.


Find in a notepad works just like the main menu Find.

Press EXE again if you want to find the next occurence, or SHIFT EXE to find the previous one.


You clear out the notepad by zapping it.


The functions available in the notepad calculator are the same as the list functions in the main calculator:
SUM= adds up the numbers.
ITEMS= counts how many items are in the calculation.
MEAN= VAR= and STD= give the mean, the variance and the standard deviation.
MAX= and MIN= give the highest and lowest number.

The results are shown like this:

You can add, delete or change numbers and then recalculate the expenses whenever you like. You don't need to delete the results after the = signs each time - they are changed automatically when you recalculate.

The functions operate on all numbers in the notepad, even numbers which come after them.

Decimal places in results of calculations

Normally the results of calculations are rounded to 2 decimal places. The maximum number of characters in the result is 15. You can change this by typing the FIX= functions somewhere in the notepad. The format of the function is FIX=x or FIX=x,y where x is the number of decimal places and y the maximum number of characters up to 15 in the result (including the point). The point of setting a maximum number of characters is to make sums align neatly.


This sorts the lines of the notepad into alphabetical order. All the lines are sorted except the first title line.

The sorted notepad is shown:
JOHN ADAMS          

Numbers as well as letters are sorted into order. so if you inserted priority numbers at the beginning of a to-do list you could then sort the lines into priority order.

Sorting requires twice as much free memory space as the size of the notepad.


This adds a number to the start of each line. All the lines are numbered except the first title line.

The numbered list is shown:
1) Alison
2) John
3) John Adams       


This prints out the notepad:

If you want to cancel, press ON/CLEAR.

If there is no printer attached. you get the error message DEVICE MISSING. For more details about printing, see Chapter 17.

Password protection

Password protected notepads are the ideal place to keep your cash card numbers, and other private data.

If you want to set a password on a notepad:

You are asked to type in the password twice. As you type in the password, #'s appear on the screen.

From now on nobody can get into this notepad without first entering this password.

If at any time you want to change it, load the notepad, then select Password again. You first enter the existing password, then the new one twice.

If you no longer want a password, just press EXE as the new one.

Warning: If you forget the password you will never be able to get into this notepad again.

The notes are encrypted which means that nobody can read them even if they copy them to another computer, or have the programming skill to find them where they are stored in memory.

Using more than one notepad

When you first enter Notes. you enter the current notepad which is called NOTEPAD. However, you can also have a number of notepads, each of which is in a file. There are two ways of doing this:

Creating a new notepad

Select New, and if there are notes in the current notepad which you haven't saved, you are informed that data has changed since you last saved:
New? Y/N

If you want to save the unsaved notes in a file first, press N and you can then select Save. When you've saved the notes in a file, you can select New again. If you want the unsaved notes to be discarded, press Y.

You are then shown an empty notepad with this name.

Loading a notepad

When you have more than one notepad, you always come into the one you used last. If you wish, you can then select Load to load a different one.

If you have made changes to the notepad you used last and you haven't saved them, you are warned that DATA HAS CHANGED. You can then load anyway or go back and save first. just as when you create a new one. Then this screen is displayed.
Load A:EXPENSES     


Choose a notepad to load in one of the following ways:

For further information on file lists see Chapter 12.

Saving a notepad

At any time, you can save the current notepad under a different name. For example to save the notes you've got in the main notepad under the name TODO:

You could then zap the notes in NOTEPAD to clear it.

Dir, Copy and Delete

These three menu options work in exactly the same way as they do on the Utils menu, except that you do not need to choose the file type, (notes). See Chapter 15 for more details.


Using the main notepad

Your notes will still be there next time you come into the notepad.

Clearing the notepad

Organiser bar.

10 World dialling codes and times

In World you first set your home location. You can then find out the dialling code from there to any major city in the world. It also provides the time in these cities.

Note: If you want the city times to be accurate relative to GMT, and the clocks are currently forward an hour in your home location, you should have set Daylight-saving in the Time option. See Chapter 2.

Resetting the home location

The home location is the one displayed on the clock when you select Time from the main menu. Whenever you reset the home location, the time changes on the clock to reflect the different time zone.

To reset the location:

The first time, you are shown a screen showing you how to dial New York from the current home location. On this screen you can use DOWN and UP to browse through the list of cities and countries.
 New York Manhattan 
  Sun  1 Jan  9:00a
  Dial: 010 1 212

To set your location:

As soon as you start typing, a city or country is displayed on the top of the screen.

For example, if you wanted Amsterdam and just typed in AM the first name displayed would be Amman:
Set home: AM_

You could then use DOWN to see the others starting with AM or supply another letter - AMS.

You return to a screen which shows you how to dial New York from the new home location:
 New York Manhattan 
  Sun  1 Jan  9:00a
  Dial: 09* 1 212

If you now press ON/CLEAR to return to the main menu you will see that the time on the clock has changed if appropriate. If you select Time, you will see the new home location displayed.

Finding out codes and times

You can now use Find to look up the dialling code from your location to any major city in the world. You are also told the current time in that city.

The Find prompt appears, and a matching city and country are displayed:
Find: LIS_

You are shown the dialling code and the time like this:
  Wed 31 May 10.00a
  Dial: 010 351 1

If you want to see all 650 cities and countries. you can type A then use DOWN to scroll down.

Note: Obviously the time in the country you are dialling may be out by an hour at certain times of the year if the clocks are put forward there. The time given is always relative to G.M.T.

Dialling codes

, Indicates that you should pause at this point in the dialling

? Indicates that there may be a way of dialling but it is inconsistent. Ask the operator.

/ Indicates alternative dialling codes.

No code Means you can't dial direct, but only through the operator. (This may change at some time as countries introduce the service.)

Note: No dialling code is shown when you find your home location.


If you find a country rather than a city. you are shown the dialling code to that country and the time in its capital city.


These come after the city or country name. E.g:
Germany West
Berlin East
Korea North

So, to find North Korea type KOR.

11 Time

This chapter shows how to put the clock forward or back one hour, and how to use the stopwatch and timer. Setting the clock is covered in Chapter 1.

Putting the clock forward or back one hour


A (D) indicator appears next to the time on the clock, and the time goes forward one hour.


The (D) indicator disappears, and the time goes back one hour.




It records in increments of 0.05 seconds. To start the stopwatch, press EXE. Then use the following keys:

Return to the ordinary clock again with ON/CLEAR.



Mins:00   Secs:00   

The cursor is on the minutes, ready for you to set the time you want to count down from.

When it gets to zero. the alarm sounds for one minute.

Note: While the stopwatch and timer are counting. no Organiser alarms will go off.
