Thanks Kris, René, and others for copious input and assistance.
I presented "Pervasive Plumbing - Pipelines for Everyone" last week at
the VM Workshop.
Turns out that the title was not clear enough. (At least two people
would have been interested in the session if they had known that it was
*not* another CMS Pipelines talk.)
This implementation uses standard Unix/POSIX services to effect
controlled flow and multiple streams. It does not require Java.
Stages run as ordinary Unix/Linux programs and can be written in any
language.
Most stages are written in C, but there is a sample stage in Rexx and
another in COBOL. (really)
The plan was to release XFL 1.0.0, but I missed a variable when merging
some of the logic from development sources to deliverable sources.
The effect was that 'pipe' would not handle CMS-style options processing
(inside parens instead of dashed like Unix).
That has been corrected, so now XFL 1.0.1 works as intended.
Yes, this Unix program also handles CMS-style options.
The project has gone by several names. Dave Jones suggested "Conduit".
XFL is the prefix assigned by IBM.
There are still issues. For one thing, the parsing logic needs to be
moved from the 'pipe' command source into the library. Stage start-up
needs a better function. (Primary, secondary, and so forth can be
unclear with the current start-up function.)
Most significantly, it needs more stages.
There are presently only enough stages to demonstrate that it works.
I have taken a sample from the 300+ stages in CMS Pipelines as "to be
implemented real soon now".

The latest source has been built for Linux-s390, Linux-x86_64,
Linux-arm, FreeBSD-amd, SunOS-i386 (OpenIndiana), and CYGWIN.
Those builds will be available in the Chicory collection.

I've got 2 versions on Windows
- The one I often use (mainly in my REXX code to maintain my photo's):
This document describes OS/2 Pipelines version 0.99 for OS/2 and version
1.00.52 for Windows and AIX.
The OS/2 version is available as OS2PIPE package on the OS2TOOLS
repository.
The (beta) Windows or AIX versions are requestable from the author. On a
VM/CMS command line enter:
REQUEST WINPIPE FROM FDB AT NLVM
or:
REQUEST AIXPIPE FROM FDB AT NLVM
The initial versions of the OS/2 Pipelines program and this
documentation (up to version 0.53) were written by Mark VanTassel during
1993 and 1994. Since Mark has left IBM (ISSC) in September 1994, ownership
of the OS2PIPE package has been transferred to Frans de Bruijn (FDB at
IBMNL or *f...@nl.ibm.com<f...@nl.ibm.com>* ).
Ronald van der Laan wrote the first version of the BUFFER, COLLATE,
LOOKUP, and SORT stages.
- As it misses quite some stages that I was used to on z/VM, and as it
had some bugs in handling FIELDSEP/WORDSEP and SUBSTR, I looked for another
implementation and found "PCPIPES" or "PC-PIPES" by James Johnson. Back in
2011. It was more complete, but much slower. I had quite some contacts
with the author atjamesjohn...@centurylink.net As I had too many
problems with accented characters when reading files and passing then
between REXX and PC-Pipes, I gave up.
So, I still use WINPIPE on my Windows 10. Incomplete, but the basics work
perfectly well. Except for VARLOAD, that causes REXX to abend. So I coded
around using STEM

hello gang --
I've been trying to gather a list of pipelines implementations apart
from CMS/TSO.
Specifically, I know about NetRexx Java Pipes, and I think there was
another Java implementation. I also found an implementation in Swift.
Are there others? This is my current question.
I'm scheduled to present at the VM Workshop on "Pervasive Plumbing -
Pipelines for Everyone". My own attempt has finally borne fruit. So many
stages to write. So little time. I want to make sure that the talk
covers sufficient ground and gives credit to the other developers.
thanks!
