Forum regular Suefan sent me a copy of this routine, and I posted it ages ago: but that was from a TOTP2 rebroadcast, with all those smart-alec remarks plastered over the bottom half of the routine. Still, I was and am happy to get it. But unsatisfied, he continued his search, and has succeeded in tracking down this unspoiled version. Hooray!
Thanks again to Suefan for taking the time and trouble to find and send this.
