Hello, I need a better source of documentation for GPC... I did read the documentation on agnes but I still have a feeling of missing something when I use the compiler.... Most of the time I go by intuition, having used for many years various Pascal implementation I end up with a trial and error process to functions, libraries and RTL function calls... Is there a place where we have a list of the function and there call parameter structure. I am using right now a generic Pascal reference and an old Borland Pascal language definition with a grain of salt and lots of little test programs but I find that so time consuming. Hopefully some people on the list are more experience with the GPC more specific issues and can help guiding me to a better reference. Thanks Claude.
