D. Reserved Variables
The calculator uses the following reserved variables. These have specific purposes, and their names are used as implicit arguments for certain commands. Avoid using these variables’ names for other purposes, or you may interfere with the execution of the commands that use these variables.
You can change some of the values in these variables with programmable commands, while others require you to store new values into the appropriate place.
System Reserved VariablesMost system reserved variables (except ALRMDAT, IOPAR and PRTPAR ) can be stored with different contents in different directories. This allows you, for example, to save several sets of statistical data in different directories.
