Thank you Phil for the suggestion. I did not know about H2PAS. But; yes I have successfully used a dll written in c/c++ and FORTRAN for use in Delphi. I even wrote a full translation, no dll needed, from c/c++ and FORTRAN to Delphi Pascal. The full translation ran noticeably faster than the original code.
I am looking for c/c++ source code or even a compiled dLL to start with. I do not expect to find layers of code to work with. Al though some code is broken up into numerous tini weeny little pieces. Probably more code than necessary. I like one file using the KISS coding rule!
