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.
