Very interesting, all that.
I am living just about 10 km from Boeblingen.
I was a MVS guy until some weeks ago (well, I worked with VSE in the
early 1990s,
but never since). I almost never had the need to deal with VSAM files,
because
all my customers used DB2. Now, all is different. I feel suddenly pushed
back in the 1990s :-)
30 years younger :-)
Couldn't imagine that my questions would start such a discussion :-)
Have a nice day,
thank you

Just for the record, the REXX developer for IBM in 2001 was Ursula
Braun-Krahl. I believe she retired.

There have been a lot of cases where z/OS was behind z/VSE.
First, a CA level backup/restore program for VSAM that was offered to
z/OS but they turned it down. Much faster than EXPORT/IMPORT and even
faster than CA-Faver. We have had it since the early 80's.
Second, we support FBA and SCSI disk.
Third, the JES2 support for virtual printers/punches is missing a lot
of things that POWER on VSE supports. This causes me a lot of work
when I do a z/VSE to z/OS conversion.
Historically, we have had NJE over TCP/IP for many years before it
was added to JES2.
We actually had TCP/IP available on VSE before there was any offering
for z/OS.
We have had real data-at-rest, field level, automated encryption
since 2006. (This is actually one of my products.)
Yes, there is a lot of stuff z/OS has that VSE does not, but that
does not mean VSE does not have some stuff z/OS does not have.
BTW, it is my understanding that REXX/VSAMIO on VSE was written by
Boeblingen as a white-room project that did not use any of the Armonk
stuff. Boeblingen had a real sharp REXX developer back in 2001 (yes!
2001, 19 years ago). The z/VSE VSAMIO routine will even read/write
CICS files via cross-partition communications using CICS as a
FOR/DOR. And, it's all IBM code that could be ported to z/OS is the
z/OS developers would get off their high-horses and ask for the code.

Dang it, how is it that the fine VSE developers in Boeblingen can
get permission from Armonk to provide VSAMIO for REXX/VSE but users
of z/OS REXX have to install the open-source RXVSAM package to
enable dealing directly with VSAM files from REXX programs?

Subject: Re: VSE related questions
Thank you all for your valuable advice.
I already found many of the answers to my questions, and some books:
REXX for VSE:
https://www-05.ibm.com/e-business/linkweb/publications/servlet/pbi.wss?CTY=US&FNC=SRX&PBL=SC33-6642-09
User's Guide for Barnard FTP:
ftp://public.dhe.ibm.com/s390/zos/vse/pdf3/ipv6vse/iesipu41.pdf
REXX VSAMIO and some examples in the FTP user's guide answered all
my questions a) to d) I will try all this next week at my customer's
site.
(both REXX EXECIO and FTP can work with VSE libraries directly,
which is still more interesting for my use case)
Thank you again,
kind regards
Bernd
