The FILE= option in
the CONTENTS statement of the CATALOG procedure is the only portion
of this procedure that is host specific. Under
z/OS, if the value
that you specify in the FILE= option has not been previously defined
as a fileref (using a FILENAME statement, FILENAME function, TSO ALLOCATE
command, or JCL DD statement), then SAS uses the value to construct
the physical filename.
In the following example,
if the SAS system option FILEPROMPT is in effect, a dialog box asks
whether you want to allocate the external file whose fileref is SAMPLE.
If you reply
Yes, then SAS attempts
to locate the external file. If the file was not previously allocated,
then SAS allocates it. To construct the data set name, SAS inserts
the value of the SYSPREF= system option in front of the FILE= value
(in this case, SAMPLE), and it appends the name LIST to it. In this
example, if the value of SYSPREF= is SASDEMO.V9, then SAS allocates
a physical file that is named SASDEMO.V9.SAMPLE.LIST.
