Oh noes,

I think YASL is the term your looking for Wayne.
Having said that, how many scripting languages do we have on z/OS? REXX,
CLIST, perl or propriety vendor languages like NCL etc. How many of them
can do mundane tasks like parsing XML? That's easy in Lua
http://matthewwild.co.uk/projects/luaexpat/examples.html. How would you
parse
XML? Code a COBOL/PL/1 program. Use XML system services in assembler.
Use C++ xereces. None of those solutions are simple.
If you wanted to write a quick web app would you choose WebSphere Java,
CICS? Yet again piece of cake in Lua http://www.keplerproject.org/ or
the bleeding edge Luvit framework which is a node.js clone, already in
production at rackspace http://luvit.io/.
Very small language easy to learn http://tylerneylon.com/a/learn-lua/.

Go Forth and multiply comes to mind.

But his recommendation(s) need serious consideration.
Lua - yet another "language" to maybe have a look at. I seem to have about half a dozen
already "half-looked" at.
What you have to consider is what languages are available on z/OS. The cupboard
is pretty bare other than JVM languages which don't run in the native
environment. Most people consider mainframe modernisation to be replacing green
screens with GUI front ends. That's all well and good but what I really yearn
for are the tools that I'm used to on other platforms. I chose Lua because its
easy to port and I was already using it to create cross platform mobile apps
with the corona SDK. The z/OS ports of python and perl are stale. Ruby and
JavaScript are difficult to port to EBCDIC.
It's true that there are far too many languages to choose from. All of them
have strengths and weaknesses. Although Lua is well known as a video game
language and notorious for the flame/stuxnet viruses it runs brilliantly on
z/OS. Its so fast my colleagues thought I was tricking them and running
compiled code.
Quite a popular language
