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


FORMAT

  EXISTF pathname ...


  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

  1. $ if existf my_file then args "The file is there."    Test for "my_file"
     $_else args "Out of luck." endif                       which does not
     Out of luck.                                           exist.
