There's no need to be quite so verbose with dc. ;-) Thanks to tpr5, I
now have a nice infix to rpn converter (show me the weasel that claims
golf is a fruitless pursuit and I'll show you a weasel).  With a
little hand holding and post munging, it converts Piers script
straightforwardly into the following 166 character dc ditty.

echo $* 'dsy19%sgly100/sclcd4/-8lc*13+25/-19lg*+15+30%shlhd28/1lh28/29lh1+/*21lg11/-*-*-silyd4/+li+2+lc-lc4/+7%sjlilj-sl3ll40+44/+smll28+31lm4/*-sdlyn32Plmn32Pldp'|dc

Suboptimal but effective.  Even calls itself, "sily"
