Important Notice

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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

─────Creating Overlays──────────────────────────────────────────────────────
 
     You can specify program overlays on the command line. Overlays let
     several program modules use the same memory area, one module at a
     time. When needed, a module is loaded from the disk.
 
     Overlays may be used only in DOS.
 
     The modules to be overlaid are enclosed in parentheses. For
     example, the following command line instructs FL to overlay
     modules OVER1.FOR and OVER2.FOR:
 
          FL MAIN.FOR (OVER1.FOR OVER2.FOR)
