Several global variables have been pre-assigned by the command interpreter.
They may be used anywhere you would use your own variables.

The table below briefly describes each of the global variables.
To get more complete information about a specific variable,
type the variable name (e.g. "HPCIDEPTH") at the HELP system prompt.

For additional information, enter FUNCTIONS, EXPRESSIONS, and
OPERATORS at the HELP prompt.

The global variable types include:

o READ ONLY variable (cannot be modified).
o READ/WRITE variable (can be modified).
o A standard MPE/iX JCW.
o Integer format.
o Boolean format (TRUE/FALSE).
o String (ASCII) format.
o Not programmatically accessible. These CI local variables may
be accessed through the COMMAND or HPCICOMMAND intrinsics, but
not with the HPCIGETVAR, HPCIPUTVAR, and HPCIDELETEVAR intrinsics.

All user-created variables may be modified and deleted. However,
Hewlett-Packard-defined variables may not be deleted. JCWs may be
considered integer variables with legal values ranging from 0 to 65,535
and with bits 16 and 17 (bit 0 being the leftmost bit of 32 bits)
having special interpretations (for example, if bit 16 is set, the JCW
setting is FATAL ).
