I doubt it. But I'm curious. Why do you need the precompiler to ignore the things aren't going to be compiled anyway? Of course you could emulate this with a 3 stage method. First, run the C compiler with the PPONLY option to run the C precompiler, which would output the C code with all the #include and other #... functionality done with the output going to a temporary file. Then run the DB2 precompiler against that output as its input, writing to another temp file. Then run the C compiler again against the DB2 precomiler output file. Seems a bit unusual, to me. Have you tried the DB2 coprocessor? As I understand it, it is dynamically invoked from the C compiler when it sees an EXEC SQL statement. So the C compiler will process the #ifdef's. http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/dsnapj15/5.1.1.1.2 -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
