Compiling CASE - back to the fray

[primerd!DOUG@ENX.Prime.PDN]

I might note that the equivalent case in the PRIME PL/1 compiler 
(select(value); when(1)...; when(2)...;) is essentially broken down
to the nested if type construct in the IL representation and then
optimized by the backend into a computed GOTO.  This has the feature
that if it was 'nicer' to write the code as nested IFs then the code
will still be optimized.
