Minoru, When you look back some years from now at the command: PIPE tape 181 | mm T | cons you may wonder from where the "MM" stage came, since you cannot find it in any CMS Pipelines manual.
In my humble opinion it is a good practice when specifying home-grown stages, as opposed to Built-In-Feature (BIF's), with the REXX stage. Thus your command would become: PIPE tape 181 | REXX mm T | cons Anyone glancing at the command should immediately be able to tell that the "MM" stage is not part of the distributed CMS Pipelines, and not to bother looking for "MM" doc in the IBM manuals. Using REXX also causes Pipes to not bother looking for a BIF stage, instead searching for an external function. This has two advantages, 1) it's faster (although in this case it would be immeasurable) and, 2) if at some point in the future IBM distributes an MM stage as a BIF, your code will continue to work. Being somewhat cryptic, "MM" is unlikely to be chosen as an IBM stage name, but getting into the habit of using the REXX stage can save you later when you write your own stage with a name that IBM may define. Using the "REXX" for home-grown external stages falls into the same category of "good coding practices" as beginning REXX execs (where possible) with: address COMMAND Mike Walter Hewitt Associates The opinions expressed herein are mine alone, not my employer's.

Assume that file name and file type of the Piplines REXX file are "MM REXX". The VMFPLC dumped tape is mounted on and attached with virtual device address 181. Enter following PIPE command to restore the files on the tape into disk mode "T" disk. PIPE tape 181 | mm T | cons I hope that this might help someone in the future.
