But if someone here thinks it can, then it would make >mine easier :) You may want to give doxygen a try. It includes a preprocessor and can be configured what macros to expand. That may give you the processed source files as you want (and some nice documentation as well :) I have never used it for that purpose but I think it can do it. If that doesn't work you may want to write a script to filter the text files. sed can probably do it. bye Fabi
