STARTEQW

If it exists, the STARTEQW variable is evaluated whenver an element in the Equation Writer is selected.

STARTERR

If it exists, the STARTERR variable is evaluated whenever an error message is displayed.

STARTOFF

If it exists, the STARTOFF variable is evaluated when the calculator turnsoff automatically.

STARTRECV

If it exists, the STARTRECV variable is evaluated when the user presses RECV from inside the Filer. It takes as
an argument, the selected argument's name.

STARTSEND

If it exists, the STARTSEND variable is evaluated when the user presses SEND from inside the Filer. It takes as
arguments the selected object and its name.

STARTUP

If it exists, the STARTUP variable is evaluated when the calculator warm starts.
s1, s2, ...
The ISOL and QUAD commands return general solutions ( as opposed to principal solutions ) for operations. A
general solution contains variables for arbitrary integers or arbitrary signs or both.
The variable s1 represents an arbitrary + or
sign. Additional arbitrary signs are represented by s2, s3, etc.
If flag
1 is set, the ISOL and QUAD return principal solutions, in which case the arbitrary sign is always +1.
TOFF
TOFF contains a binary integer #xxxxh that defines the number of clock ticks until the next calculator auto
shutoff (with a default of 5 minutes or 6*60*8192 ticks)

VPAR

VPAR is a variable in the current directory. It contains a list of parameters used by the 3D plot types. The main
data structure stored in VPAR describes the "view volume," the abstract three-dimensional region in which the
function is plotted.
