How to make COM files with JRT PAscal?
If you want to know what their linker does, just read the Users Guide,
page 118 for Release 3.0. It will just build ONE executable .INT file from
several (if you don't "LINK", it defers the loading of invoked INTs until the
program needs them). This isn't what is usually named a linker.
Your IN2 file is a RENAMEd copy of the original main program file. The new
main INT is a concatenation of the original main INT with eventual additional
modules (such as TAN,LOG, you name them).
