When accessed, the variable
contains the return code for the service request. SAS uses the VDEFINE
user exit to define
variable-name as
a character variable of length two, placing it in the pool of functions
that are automatically specified.
For example, if ISPEXECV=SASEXEC,
then you could do the following from an ISPF panel:
&SASEXEC = 'DISPLAY PANEL (XXX)'
IF (&SASEXEC ¬= '00') ...
To display the current
settings of your ISPF options, use PROC OPTIONS GROUP=ISPF.
