That's it, thanks! Dunno why that didn't turn up for me in Google. Ah, well.
I've been starting to do more work in REXX leaning on my ARexx experience. There's a pretty good Rexx interpreter out there called Regina. It works in Windows and Unix (compiles fine for Solaris.) Using the "rexxcps.rexx" script, I found that my 50MHz 68060 A4000 runs about 11,000 clauses per second versus 1.4 million for my Core2Duo XPx64 laptop and 330,000 on my Solaris 8 AMD K6-3+ machine.
