Hello, After some experimenting, I produced an OS/2 dynamic link library (DLL) with GNU Pascal that I could call from another application. Perhaps this is common knowledge but I do not see it documented anywhere. The following seems to work compiled with the latest emx distribution of GPC using "gpc -Zomf -Zdll cube.pas cube.def": unit cube; { a simple function in a DLL} interface function cubit(x:integer):integer; implementation function cubit(x:integer):integer; begin cubit := x*x*x; end; end. You have to be careful in the module definition file to list the function with only the first letter capitalized or LINK386.EXE will complain: /* module definition file for Cube dll */ LIBRARY CUBE EXPORTS Cube @1 Allan D.
