The pages on this site contain documentation for very old MS-DOS software,
purely for historical purposes.
If you're looking for up-to-date documentation, particularly for programming,
you should not rely on the information found here, as it will be woefully
out of date.

All the loaded modules are shown in the list box. Choose
the one you want to be the main module.
When you start running a program, the first executable
statement in the main module is always the first statement
executed.
