SAS Companion for the OS/390 Environment

Displaying Information about External Files

You can issue the FILENAME command from the command line to display the FILENAME window. This window lists all current SAS filerefs plus the name of the physical file to which each fileref has been assigned. Files that were allocated externally (with a JCL DD statement or with the TSO ALLOCATE command) are listed only after you have used them as filerefs in your SAS session. For more information about the FILENAME window, see SAS Language: Reference.

Under OS/390, three additional windows--FNAME, DSINFO, and MEMLIST--also provide information about external files. For information about these windows, see Host-Specific Windows in the OS/390 Environment.
