Greetings to the -L,

I'm looking for information on the sequence of events performed by the HP COBOL II/iX compiler.

1) Specifically, when does the compiler evaluate the following and in what order:

- COPY Statement
- COPY ... REPLACING Statement
- REPLACE Statement
- $ Preprocessor Commands
- Macro Evaluation

2) Is the above performed in a single or multiple passes of the source.

Reason for questions:

Somebody contacted the GnuCOBOL project regarding the CobolMac preprocessor that I wrote. It seems that in some of their programs they have redefined macros and were asking how CobolMac could be changed to implement this feature.

I have been looking at how this could be done but realised that I needed to increase my understanding on how the HP compiler worked. Any information on the above, and anything else you think might be relevant, would be appreciated.

regards,
Robert W.Mills
