Operation Notes
FCHECK is used to determine the error conditions of the last failed FOPEN intrinsic call (even
if a file number was not returned) by setting the
filenum parameter to zero. In this case,
only
fserrorcode returns valid information.
Do not use FCHECK to determine error conditions of a last failed HPFOPEN call; error
conditions are returned in the HPFOPEN
status parameter.
Condition Codes
CCE (2) Request granted.
CCG (0) Not returned.
CCL (1) Request denied. The file number passed by
filenum is invalid, or a bounds
violation occurred while processing this request (
fserrorcode =73).
