Note this code requires the Watcom C/C++ compiler v 10 and above to compile correctly. You also need the DevHlp library available from the OS2page one page back. Note this library has been written for use with Watcom, it takes advantage of register calling conventions. As a result other devhelp libs from other sources will not work correctly.
