existf -- Check for existence of an object.
usage: existf pathname...



DESCRIPTION
     existf reads the object pathname(s) you supply and checks to see if the
     object exists.  If the object does exist, existf returns with a good
     program status (pgm_$true).  If the object does not exist, existf returns
     an error status (pgm_$false).


ARGUMENTS
     pathname required
                    Specify the object to be checked. Multiple pathnames and
                    wildcarding are permitted.  If you specify more than one
                    pathname, all the objects must exist for existf to return
                    true.

EXAMPLES
     Test for my_file which does not exist.

     $ if existf my_file then args "The file is there."
     $_else args "Out of luck." endif
     Out of luck.
     $
