What's the obstacle (not to popularity, but to TSO toleration)?
NetRexx is basically a translator that compiles REXX code into Java
source code. That's quite unique. All the other JVM languages compile to
byte code. The same
restrictions apply to running Java in a TSO environment. You would have
to spawn a Java JVM (yikes!). The TSO and ISPF interfaces would have to
be done using JNI. It sends a shiver down my spine just thinking about
it. I think you can forget about address TSO and address ISPEXEC
environments. NetRexx doesn't support command environments like
mainframe REXX, it uses classes.
