printf() needs a console to print to and Win16 does not support consoles.  Compile your project as QiuckWin (or something similar).

OK, first thing first: Native Win16 applications cannot use printf() for lack of a console.

Options:

1. Compile as a QuickWin application.  It "maps" the stdio to a window that simulates a console.  I have no idea why a CGI cannot be a QuickWin application, but then, I have no idea how a CGI is different from a "normal" application.

2. Compile it as a DOS application.  Obviously all functionality provided by Windows will be unavailable.  A DOS program can run under windows without a problem.

3. Move to Windows95/98/NT and compile the program as a console application.

4. Create a window and a DC in your application and use TextOut() APIs for output.

5. Create an edit box in your application and use EM_SETSEL and EM_REPLACESEL messages to display output.

To summarize:  Either compile for a platform that supports a console (QuickWin, Win32 or DOS) or manage the output yourself using Win16 APIs or controls.
