is the name of the variable.
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.
Related instructions are SETPFSVAR, DELETEPFSVAR, and
LISTPFSVAR.
