Launcher is an assembly language program which avoids memory consumption while DOSMENU is running. Note however the bugs still need to be resolved (it works, but it corrupts memory causing crashes when executing certain programs, e.g. Commander Keen 1)
1) We deallocated our stack, which meant it could be overwritten by the programs we launched. FIX: reserve 256 bytes for stack, and switch stacks at start of launcher, before deallocating memory This solves problem where we would crash upon exiting certain programs, such as Commander Keen 1. 2) We couldn't run .BAT files via launcher FIX: in dosmenu.c, change command to be executed to be %COMSPEC% (presumably COMMAND.COM), and put /C before arguments This solves problem where programs launched by batch files would not start if launcher was enabled.

Use a separate executable written in assembly to maximise amount of conventional memory available to programs being run from the menu.
