is the name of the variable (uppercase characters only).
D optionally specifies that the variable is to be deleted after recovery.
Remarks This function is used to recover variables registered to be saved at power
failure by means of a SETPFSVAR statement and returns either -1 on success
or 0 at failure.
If a D flag is included, the variable is deleted after it has been recovered.
This can be used to make sure that the variable is up to date and that no
old obsolete value is recovered.
The variable name is limited to a length of twenty characters.
Related instructions are SETPFSVAR, DELETEPFSVAR, and LIST-
PFSVAR.
