Using the AFP Reblocking Program

When you transfer AFP files from your workstation to the z/OS® host, the file transfer program blocks the data records so all record lengths are equal. PSF for z/OS cannot process AFP files in this format and, therefore, cannot send them to the printer. A program included with PSF, however, can convert the records to a format that can be used by PSF. This program, the AFP Reblocking Program (AFRREBLK), reblocks the AFP file data that is transferred from your workstation to the z/OS system. You can then print this reblocked data in the same way you print other z/OS documents.

The AFP Reblocking Program includes:

AFRREBLK

A profile that the user can optionally set up to specify the default naming conventions used when an AFP file is reblocked. Found in the SYS1.SAMPLIB library.

AFRREBLK

The exec that reblocks AFP files. Found in the SYS1.SAPSEXEC library.

AFRREMSG

The exec that provides status and error messages. Found in the SYS1.SAPSEXEC library.
