- What operating system are you running under? What compiler are you hoping
- to use? If you are hoping to support such a wide range of devices you
- will have substantial problems (I speak from experience here) and under
- DOS may find it most practical to hook INT 24H- if you refer to
- appropriate technical info you will find that there is a technique to
- return straight to the application with an error code. I can warn you
- however, that you will be getting into _very_ deep water here- the code
- is not at all simple, cannot be expressed in a high-level language (i.e.
- you will need inline assembler and an intimate (I'm tempted to say
- gynaecological) knowledge of the stack state) and may vary depending on
- the memory model in use, and I admit freely that I do not know what would
- happen if you attempted to run under Windows 3.x, Windows '95, Windows
- NT, OS/2, or a DOS emulator such as DOS Merge.
-
- You may find it easier to educate your users. :-)
