I tried converting this win32 hello.c program to pascal without success... #include <windows.h> int STDCALL WinMain (HINSTANCE hInst, HINSTANCE hPrev, LPSTR lpCmd, int nShow) { MessageBox (NULL, "Hello, Windows!", "Hello", MB_OK); return 0; } I was getting undefined references to messagebox at the linking stage. To compile I did... gpc -mno_cygwin -mwindows whello.pas -o whello.exe Thanks, Mark. -- Mark Taylor, Department of Corporate Information & Computing Services, Extension 21145.
