- There's a problem here. You can append the binary data but that won't make
- code from both EXE files work. Either the first one will work, ignoring
- the code from the second one, or the whole thing will turn into trash.
-
- However, if you still want to try it, go ahead. Here are 3 untested by
- compiling file copying programs that will only append IT2.EXE to the end of
- IT.EXE. You'll be required to make or copy files called IT.EXE and IT2.EXE
- for the use of this simple demonstration program.
