Abstract: A keyboard-programmable electronic computer utilizes a user-accessible table located in memory to allow the user to list memory addresses to be associated with various key codes corresponding to keys on the keyboard. When a key is depressed upon the keyboard, the computer checks the table for the corresponding key code and, if it is listed therein, the user-written subroutine located in memory at the address associated with the key code is performed. The user-written subroutine has the capability of utilizing both the events of key depression and the status of continued key depressions as program variables.
