Here's the first program I put into any new RPN machine I play with:

%T - Return the percent that X is of Y

Code:

01 LBL "%T"
02 1/X
03 %
04 1/X
05 RTN

Derived with Joe Horn one late Friday night at a PPC meeting, around 1982-3? Cliff Stern may have been involved too. We celebrated by going to get 'breakfast' at Denny's at around 2am when the meeting ended, a long tradition after PPC meetings at the time.

Edit: Forgot to say thanks Werner, for a handy new tool for the toolbox!
