13h DP$SAVE save screen state
Input - none -
Output - none -

Saves the current screen state including the cursor position and status.

Note that since this routine saves the screen state in a static buffer, calls to DP$SAVE and DP$REST cannot be nested.

Note that this routine should not be called unless alarms are disabled as the alarm software calls this routine as well. Also the pack sizing routine (PK$SETP) uses these calls when displaying "SIZING PACK B" etc.

Errors - none -
