PSS Files

You can only change logical unit assignments. The entries PSSPRT01 through PSSPRT15 are used for CA Ideal report output, LIST statement output, and PRINT command output.

VSE Report Work Files

Do not change the entries IDRWK01 through IDRWK15. RDF uses them internally when processing sorted reports. They are not SORT work files.

• Block size-Physical block length. This information is obtained from
  the dictionary when the dataview is cataloged. You can override it with an ALTER PROGRAM command or ASSIGN DATAVIEW command before the run. At runtime, the block size is stored into the ROSFD entry before opening the file.

  The block size specified in the ROSFD is the maximum block size that you can use. If a dataview is opened with a larger block size than the maximum specified, a runtime error occurs with an I7 dataview status code.

  For tape, print, and punch files use the BLKSIZE parameter. For disk files, use the IBLKSZ and OBLKSZ parameters. IBLKSZ is the maximum block size. OBLKSZ is the maximum block size plus eight.

• Filename-The DLBL for disk files and TLBL for standard-label tape files is obtained from the dictionary when the dataview is cataloged. This name overrides the DTFNAME parameter on the ROSFD before opening the file.
• Logical Unit Assignment- For standard-label tape (SLTAPE),
  non-labeled tape (NLTAPE), printer (PRT), and punch (PUNCH) files, the default assignment comes from the ROSFD entry. You can override it with an ASSIGN DATAVIEW before the RUN command (see the Creating Dataviews Guide) or with an ASSIGN statement executed before the first FOR construct referencing the dataview.

The logical assignments for disk files are made entirely with the JCL.

If a run needs to access more than one sequential file dataview of the same type (for example, two disk or three standard-label tape files), then you must add new IDSYSFT entries. To add a new entry, make a copy of an existing entry of the same type. Change the ROSFD label from Ixxxx1 to Ixxxxn where xxxx is DISK, SLTAPE, NLTAPE, PRT, or PUNCH and n is the next available number for that device type, in hexadecimal sequence (1-9, A-G). For SLTAPE, NLTAPE, PRT, and PUNCH entries, change the logical unit assignment to something that does not conflict with any other ROSFD entry in the file table. Optionally, adjust the block size parameter as previously described.

If multiple sequential files of the same type in the same run are referenced and there are not enough file table entries defined, a dataview runtime error occurs with an 'I8' status code.
