AC>Does REXX have an equivalent of C's switch/case or Pascal's case
  >staements?

Hi Andrew--

    The equivalent is SELECT, only it is better done.  Here is a small
example from Mike Cowlishaw's book: "The REXX Language: A Practical
Approach to Programming, 2nd Edition" (ISBN 0-13-780651-5).

_______example starts here
    Testfile myfile
    select
        when rc=0 then do
            Erase myfile
            say 'File' myfile 'existed, now erased'
            end
        when rc=28 | rc=36 then say myfile 'does not exist'
        otherwise
            say 'Unexpected recturn code "'rc'" from TESTFILE'
	    exit rc
    end /* Select */
_______example ends

    Although not shown in this example, each "when" clause in the
"select" construct can refer to a different variable if need be!  Notice
there is no such nonsense as a "break" for each "when" to prevent
automatic passage to the next one.  REXX is the programmer-friendly
language!
