delete end chars

[Colin Holgate]

This seems to work (where you have field one with the letters to check, and field 2 is the letters that might end with those check letters):

on mouseUp
   put fld 1 into f1
   put fld 2 into f2
   put offset(f1,f2) into offamount
   if offamount = the number of chars in f2 - the number of chars in f1 + 1 then
      put char 1 to offamount - 1 of f2 into fld 2
   end if
end mouseUp
