I thought there were 2 versions of the runtime system for REXX. One that was free and one you paid for and therefore licensed. If this is still true, I suspect the differences between the two versions is related to either tighter code, more functions or both. I've truly never checked it out. I was under the impression that you can compile your REXX code and then distribute it license free with the alternate REXX library.
Once thing that I have found is that compiled REXX cannot be run under IPCS. I have not heard if that has changed. Anyone know if it has?

Others have pointed out the issue of external calls. I would also point out the issue of "potential gain." If the Rexx exec currently takes .1 seconds to run, exactly how much are you likely to gain from compiling it? Also note that unlike what your expectations may be, compiled Rexx code requires a separately-licensed run-time library. It will run without it, but it runs in interpreted mode, so there is ZERO gain no matter what the code is like.
