i had this problem in an application where a
piano keyboard HAS to show numerals representing
ASCII code (middle C = "60"). the keyboard
buttons must be referenced when hiliting,
changing shape etc. what i did in HC was 
store the btn ids as comma delimited items 
in a fld, store the name numbers in a function,
then use the offset function to get 
the id number in the fld.

someone on the MetaCard list pointed out that
i could name a btn "b60" and label it "60"
thus avoiding many headaches.

there are mixed emotions when MC/RR advances
let you throw away code you sweated blood over.
