*------------------------------------------------------------------------------- *-- Program...: LITE5.PRG *-- Programmer: Ken Mayer *-- Date......: 7/17/91 *-- Notes.....: The dBASE Menus are fine to a point, but there are times when *-- you may need a LOT of menu pads. This program is designed to *-- allow up to 60 menu items, although you can, if you desire, *-- set up some options as headers (these will not be chooseable *-- by the user), and you can set up conditions where an option *-- may be skipped. This routine is the original program, created *-- for my fantasy gaming procedures. It allows a user to choose *-- an item once (for you gamers, this is part of a character *-- generation routine -- when creating a character, the character *-- may improve certain skills once only ... (that's for the *-- creation ... in the update routines that option will be removed) *-- -- the user knows he's chosen that item before because the *-- color changes ... *-- Original concept by FELIXR, but I ran with it and programmed *-- it up ...
