Proposed Preprocessor Standard

Comments are requested as to what features should be in a "standard" PL/I Preprocessor.


  • %DO - Implementations seem split between supporting only a simple nonitrative %DO to group statements and the newer IBM compilers that support the complete PL/I DO-statement syntax.  A good compromise would seem to be to allow the Type-3 iterative %DO with a single iterative specification using a FIXED control variable only, as in PL/I(F).
