For a new z/OS installation, getting the IBM C compiler might not have

When pricing was based on total system capacity, existing large
installations couldn't cost-justify adding the IBM C compiler for
additional $1000's per month for experimentation and would have highly
displeased if any product suddenly required it. Being able to license
the compiler for use only in an MSU-limited LPAR provided some relief,
but still required the installation to be willing to eat the overhead of
setting up and managing another LPAR just to play with C.
There's a new kid on the block. IBM have ported clang to z/OS and it's
brand spanking up to date supporting features the IBM compiler doesn't.
You can get it for free if you download the Node.js beta. I've been
using it and it's sweet. A major issue is it's 64-bit only which may be
a blocker if you want to call legacy code. It also only runs in z/OS
UNIX so you can't compile using JCL.
