-
fileref
-
specifies the fileref to be validated.
Under z/OS, fileref can be a ddname that was
assigned using the TSO ALLOCATE command or JCL DD statement. In a DATA step, fileref can be a character expression, a string enclosed in
quotation marks, or a DATA step variable whose value contains the fileref.
In a macro, fileref can be any expression. If fileref is a literal fileref name, it must be in quotation
marks. If fileref is the name of a character
variable whose value is a fileref name, it must not be quoted.
A negative return code indicates that the fileref exists, but the physical files associated with the
fileref does not exist. A positive value indicates that the fileref is not assigned. A value of zero indicates that the
fileref and the external file both exist.
