Epstein) Subject: Conditional Compilation (CoCo) X-Mailer: I expect to have alternative CoCo definitions available for review within a couple of weeks. One of these alternatives will be CCF. Another alternative will take into account existing cpp/fpp definitions (where fpp is defined as a Fortran-like cpp). I will begin answering recent CCF questions as soon as the cpp/fpp alternative(s) are close to solid. At one time, I was quite familiar with existing fpp definitions. This, however, was before Fortran 90. I have asked a couple of vendors for their fpp definitions and have already learned of some changes to these pre-Fortran-90 fpps. If you have an fpp, please send me a soft copy of your definition. If the below questions are not answered in this definition, please also send answers to these questions. I will assume that any information you send to me may be used unless stated otherwise. #SPECIFIC FPP QUESTIONS# --? recognize the Fortran INCLUDE at fpp time or offer a #INCLUDE (or both)? --? do you allow the '#' (or whatever) of a #fpp-stmt to be in col. 6? --? what is the max line length of a #fpp-stmt? (Always 132 or depends on the source form (FIXED/FREE) of the source text or ...?) --? can a #fpp-stmt be continued? If so, a max of how many lines? --? do you define the optional output file (generated from fpp)? --? can fpp names be the same as Fortran names (or must they be unique)? --? are fpp names case-sensitive (foo is not FOO)? --? do you offer fpp comments? --? can strings be "double-quoted" and 'single-quoted'? --? are there any *predefined* names? If so, what are they? --? do you offer any form of text substitution or macro expansion in your fpp (this goes beyond the task of conditional compilation, but is still an open issue)? Please explain? Thanks in advance for any input, David Epstein imagine1 +1-503-383-4846
