'ENTER' is the neutral activity and can be used for entering and
editing information before electing an activity such as 'SAVE' or
'CALC'. Pressing EXECUTE with 'ENTER' selected has no effects.
Full information editing is available for all activities. For
convenience, editing is described here with a reference to
Press MODE/HOME repeatedly until 'ENTER:_' is displayed.
The cursor appears to the right of the activity indicator. This is
your invitation to type something. As an example, you could type
your name and address. Press any key whose upper label is one
letter of the alphabet to produce that letter in the display, in
the position currently marked by the cursor. To enter a space,
press SPACE. Don't forget, you need to press SHIFT to type any of
the numbers and symbols shown in yellow under the keys. The cursor
flashes to indicate the change, and to return to the alphabet you
must press SHIFT again.
For example to enter 'ANN 28 NOV' you need to press the following keys:
A N N
SHIFT S(,) P(2) D(8) SPACE
SHIFT N O V
You will see that the display window automatically moves along
the line as you type more than nine characters. To look back to an
earlier part of the text, press <<. Use >> to move
forwards through the text. To return the cursor to the beginning of
your line, press the MODE/HOME key once.

Mistakes in your text are easily rectified with the editing
facilities of the Organiser. To delete any character from your
text, use the chevron keys to position the cursor under it and then
press DELETE. If the cursor is beyond the end of your line when you
press DELETE, the first character to its left is deleted and the
cursor moves under the vacant position.

Characters can be inserted at any point in your text, and will
appear on the left of the cursor when you type them.
For example, if you have entered 'LDON' instead of LONDON,
position the cursor under the D and press the O and N keys.
If you suddenly find that the display doesn't change when you
enter something, you are probably trying to exceed the limit of two
hundred characters per line. If necessary, edit your text to reduce
Clearing The Display
Pressing ON/CLEAR chancels the current entry and lets you start
again in the same activity. This is the key's CLEAR function.
ENTER:THE QUICK BROWN FOX
Only the activity indicator is retained, and you can now enter
something else or go to another activity. Pressing ON/CLEAR when
the current line is empty recalls the clock display and the
Organiser is reset as if you had just switched on. You can always
use this key to clear the line and escape from whatever you are
Note. The 'SAVE' and 'FIND' sessions assume that you have a
datapak in drive one only (which is how the Organiser is
Use the 'SAVE' activity to make a permanent copy of the current
line in the removable datapak. When you press the SAVE key, the
Organiser will display the indicator 'SAVE1:' and the first nine
characters of the current line.
Nothing is actually copied into a datapak until EXECUTE is
pressed, so press it when you are ready. When you do this, you will
see the cursor move through your text as the text is copied into
the datapak. When this process is completed, the activity indicator
changes from 'SAVE1' to 'ENTER', to prevent you accidentally saving
the same record twice. If you really want to return to 'SAVE',
press the SAVE key.
To conserve space in your datapak, Organiser only saves
information you have entered or edited, as opposed to information
it has produced itself. For example the indicator 'SAVE1:' is not
Although 'SAVE' has full information editing facilities,
enabling you to type and edit information with 'SAVE' selected, it
is wise to do these things in 'ENTER' until you are properly
familiar with the Organiser. Remember, every time you save an entry
you are using storage space in your datapak.
Don't use 'SAVE' if the " LOW BATTERY" warning has
appeared. If you do so, you may spoil the remaining space in
To record information in a datapak:
Prepare the information in 'ENTER' or 'CALC'.
Press SAVE to select the 'SAVE' activity.
Press EXECUTE to make a record of your text in a datapak.
The 'FIND' function is a powerful tool which searches through
your datapak for the information you wish to recall. When you press
the FIND key Organiser will display 'FIND1:_'. Organiser now
expects you looking for a record you have already saved, and gives
you a clear line in which to enter the clue for the next search. If
you didn't clear the search clue last time you used 'FIND', it is
shown now, in case you want to use it again or modify it.
To search for a particular record all you have to do is give the
Organiser a search clue that is a series of characters that matches
some part of the record you want to retrieve. (For example, 'ANN'
would be sufficient to find a record of Joanna's name and
telephone number.) When you press EXECUTE, Organiser searches for
and displays the first record containing exactly that series of
characters. If this is not the record you need, press EXECUTE to
see the next one containing the same series of characters.
A search clue does not have to be a whole word and can occur
anywhere in the record. It may consist of anything from one to
fifteen characters, including spaces, but generally three or four
characters will be sufficient to find a record quickly.
A more restricted search can be instituted by prefacing the
search clue with an asterisk. This tells the Organiser that
the search clue must occur at the beginning of the record. For
example, 'FIND1:*SUS' would find the record 'SUSAN SMITH
.....', but not 'CONSENSUS .....' whereas 'FIND1:SUS'
would find both.
To broaden the search, do not enter a search clue at all. With
the display empty except for the activity indicator 'FIND1:' press
EXECUTE to see a copy of the next record in the datapak. Press
EXECUTE every time you want to move on to the next record.
If you ask your Organiser to find a series of characters which
does not occur in that datapak, the message 'NOT FOUND' will be
shown. Press ON/CLEAR to clear the message and recall the 'FIND1:'
indicator and your original string of characters. Check your search
clue carefully and modify it if necessary. Press EXECUTE to repeat
Scanning A Found Record
When a record is displayed, you can scan it from left to right
at the comfortable reading pace by pressing >>. The record
loops round to the beginning when it reaches the end, so that you
see a continuos progression of its contents. To hold any part of
the text in the window, press << once, and if you want to
move backwards press << again. In that case you press
>> to freeze the display.
Editing A Found Record
The line of information which Organiser displays when it has
found a record is a copy of the original stored in the datapak.
Thus you can edit it, calculate and manipulate it as you please
without affecting the original.
Immediately you attempt to edit a found record, the Organiser
selects 'ENTER' and you can edit in the usual way. To clear a
displayed record (and go into 'ENTER') press ON/CLEAR.
Erasing A Record
Erasing a record from your datapak is like crossing out a piece
of written work. It is still there, occupying space, but you can no
longer read it.
'ERASE' only becomes available when the Organiser is displaying
a retrieved record in 'FIND'. Press MODE until 'ERASE:' appears to
the left of the text. Now press EXECUTE to erase the record. The
text is cleared from the display and the Organiser automatically
The record can never be found again.
If you wish to update a record, for example to alter train times when the service
is revised, you must find and erase the old record and save
the new one. Alternatively, if a large part of the old record
is still valid, you can find and edit it, save the new version,
then find the old one again and erase it. Either way, as far
as your Organiser is concerned, the old record no longer exists.
Pressing FIND prepares Organiser to find a record in the

Attempting to edit automatically selects 'ENTER'.
'CALC' is for arithmetical calculations. When you select 'CALC'
Organiser automatically behaves as if you have pressed SHIFT, and
cursor flashes to indicate that the keyboard will respond according
to the yellow numbers and symbols. (You can return to the alphabet
by pressing the SHIFT key, but the Organiser will not perform
calculations on letters).
To Carry Out The Calculation
Select 'CALC', type your calculation, leaving no spaces between
characters, and press EXECUTE.
Provided that your calculation contains no errors, the Organiser
immediately displays the result, which consists of an equals sign
and the answer. The last few characters of your entry will also be
displayed. Use the chevron keys to see the rest of the line.
If the Organiser finds any errors in your entry it will move the
cursor to the first character it does not understand, and wait for
you to correct it. (Some possible errors are: an unpaired bracket,
a letter of the alphabet, a space, a number containing more than
seven digits, or an incorrect operation such as division by zero.)
When you have made the correction, press EXECUTE to try the
calculation again. Every time you press EXECUTE the cursor will go
to the next error, until you have corrected them all.
The exciting feature of the Organiser's calculation facility is
that you can see the whole calculation, and can edit any part of it
as you wish. (Very important when your calculation can be two
hundred characters long.) Before examining this detail, a word
about numbers and symbols.
Your Organiser can deal with numbers containing up to seven
digits. You may enter numbers less than one as decimals (with or
without a nought before the point) or as fractions. For example
0.25, .25 or 1/4. To make a number negative, simply enter a minus
sign before it. Your Organiser can distinguish between this use of
a minus sign and its use in subtraction.
The Organiser recognises and uses exponential format. This is a
neat way of presenting very large or small numbers which would
otherwise use too many digits, and is explained below.
Recognising The Symbols
You will find the arithmetical symbols marked in yellow under
some of the character keys. Those you may not recognise are:
||which means 'divide by'
||which means 'multiply by'
||which means 'multiply by ten raised to the power given
by the next number'. Press this key when entering a number in
exponential format. (Only one E is shown in the display)
You can also use these symbols in general text.
A number which contains many noughts may be conveniently written
as a number between one and ten multiplied by ten to a given power.
For example, the number 2 300 000 may be expressed as 2.3
times 1 000 000.
Now 1 000 000 is ten raised to the sixth power: that
is six tens multiplied together. Therefore we may sensibly express
the number 2 300 000 as 2.3 times ten to the sixth
power. Exponential format is a form of shorthand which allows
us to write this as 2.3 E6. The E stands for 'multiplied
by ten raised to the power given by the next number', and the
six means the sixth power. Negative powers of ten are used with
'E' in a similar way, so that 2.3 E-6 means 2.3 divided
by ten to the sixth power, that is 0.0000023. The smallest value
your Organiser can accept is 1.000000 E-99 and the largest
is 9.999999 E99.
Where it is appropriate, the Organiser presents the results of
calculations in exponential format.
Organiser allows you to use as many pairs of brackets as wish
in your calculation, but only two levels of brackets
are allowed: i.e. you must not enclose more than one pair of
brackets within another pair. For instance, 3*(1+2+3*(4+5*(7-6)))
is unacceptable because there are two pairs of brackets enclosed
in another pair, making three levels at all.
Like other calculators, Organiser will normally carry out any
multiplication or division operations before addition or
subtraction. If you want to carry out any additions or subtractions
first, you must enclose them in brackets. For example, the
Organiser calculates 4*5+3 as 23. To make it add the 5 and the 3
together before multiplying by 4 you must enter 4*(5+3) which is
calculated as 32.
Editing A Calculation
Remember that a calculation can be edited just like any other
line of information, both before and after the result is displayed.
As well as making it easy to correct typing mistakes, these
facilities mean that you can perform a whole series of calculations
by editing the preceding version, rather than re-typing it each
This is useful for 'What if' analysis, where you want to examine
the effect of changing one parameter of a system, e.g. the effect
on profit of increased component price.
When you start editing the calculation the result disappears
because it is no longer valid.
If you want to use the result of one calculation in the next
one, simply enter the additional numbers and symbols to form the
new calculation and press EXECUTE for the answer. Organiser assists
you by deleting the equals sign and everything to the left of it as
soon as you start editing the original result.
The answer produced by the Organiser does not form part of the current line,
so if, for instance, you press SAVE, your calculation will be retained (as you
typed it) but the answer (which the Organiser supplied) will not. However, if
you edit the answer, it becomes the current line and can thus be saved
and generally manipulated the normal way.
Press MODE/HOME and select 'CALC'.
Enter the calculation, leaving no spaces.
Press EXECUTE to make Organiser calculate the answer.
Editing available before and after execution.
