Abstract

An arrangement to permit the operator of a Personal Computer to define functions for up to 24 different keys is described. The 25 program function (PF) keys are arranged in 2 rows of 12 keys and are located above the inboard area on the keyboard. These keys will be interpreted as 24 separate keystroke programs. Keyboards that do not have the 24 extra keys can still get the function by entering Alt- 01 to 24 on the numeric keypad. The operator can define or clear the 24 PF keys separately. Key definitions can be single or multiple key sequences. Each time a PF key is pressed, the stored keystrokes will be "played back" as if the operator had keyed the sequence. If the operator wishes to retain the key definitions, they can be stored collectively in a DOS dataset on disk.
