Why hasn't it been released as open source under the same license,
after all it's just decompression code, and given the note in the
User's Guide,
"The decompress function of TERSE was recently ported to Java by IBM
and it is available under the Apache 2.0 license and is available
here. However, that program doesn’t support VBS format either."
so that those with the knowledge can add features like EBCDIC-ASCII
translation, or incorporate the code into something with a GUI?
After a discussion with Mario at SHARE last year and some assistance
since I have been working on updating the open source Java code to
support variable length binary records.
I have it working, I have just been very slow to update the
documentation and contribute it back to the original repository.
You can see my changes here:

What I would like to do is make it available as a class that can be used
from other applications, not just a command line application. Some of
the changes and refactoring have been done with that goal in mind.
A secondary goal is a port to C# so it could run under .NET (Windows and
other platforms).
But *why* do you want it to translate EBCDIC->ASCII? The current
implementation does that, but I haven't figured out why. It makes
testing much more complicated. It seems like it would be much better to
do the translation outside of an UNTERSE implementation, and have the
compression code give you back exactly the same data that was compressed.
