It ain't as simple as in C (but then neither are bit-ands and ors). Try
using the symmetric set difference operator by casting. Something
like this might work:

	tmpbuf[i] := CARDINAL(BITSET(inbuf[i]) / BITSET(key[kp]))

You may have to fiddle with the appropriate set types to get this past
the compiler, but hopefully you get the idea.
