Front-End Menu System

A front-end menu system for PC99 which runs under DOS, Win 3.1, Win 95, Win 98, and probably NT if you run PC99 in NT.

Written in Demon Quickbasic. All files can be in the main PC99 directory and assume disks are in the \PC99\DSK directory.

The program reads the PC99.MOD file to construct a multi-page menu structure, from which selections can be made using: Edit keys (arrow keys, Home, End, Page Up, Page Down, Control Home). Mouse (single click select, double click run). Numeric entry.

The PC99.MOD file can be amended slightly, without loss of compatabiliy, by adding # MYARC to select the Myarc RAM, and # DISK:PC99.DSK (or other disks if registered) to set the nominated disk as DSK1. Exiting using Q takes you back to the PC99 menu and also removes the Myarc RAM configuration.
