Hi Peter
Jack,
One problem with your advice is that many shops don't even allow application
programmers to even use shell access to z/OS.
One of the reasons z/OS installations are going away. The dinosaur keeps
moving forward or she sinks into the tar pit.
And where exactly does one learn "to set your terminal"? What values work with
/bin/sh?
/bin/sh is only good for some old scripts. You need bash or ksh for the
real world of *nix operations.
If you come in with a reasonable xterm
TERM=xterm
export TERM
I haven't found any TERM value when using Putty to z/OS that gives anything
like access to a full-screen editor like vi or vim, even if they were already
there somewhere.
xterm should work for Putty, but you just put your finger on another
problem with many z/OS shops which is they either don't allow Linux or
they don't allow users to install a decent xterm program on Windows.
Cygwin has a very nice xterm.
For the rest, I already have a lot of regexen experience with (g)awk, and I
really don’t like the perl version, and as I said earlier, can't install python
or anything else under my limited-space home directory.
Python doesn't belong in your home directory. It should be system level.
z/Linux is off the table too, CEC's are severely overloaded as it is, but
that's a whole 'nother can of worms.
You can always play with LinuxOne for free and renew every 3 months.

I use several different Linuxen at home, but again probably because I am a
particular kind of technophile. I could learn python in any of those
environments or even under Windows, but I have no particular use for it.
It's a wonderful scripting language as well as a good scientific
language. There's nothing else quite its caliber in interpretive languages.
Advice is only as useful as your particular circumstances allow. Many of us
exist in quite constrained boxes at work with very limited ability to even make
a request to expand the scope of those boxes.
Been there, done that. But IBM is trying to help expand the walls of
that particular golden cage by marking Python "strategic". Let's see if
that makes a diff.
