Abstract
An electronic computer is provided with a numerical keyboard, a microprogrammed CPU, as well as RAMs and ROMs, some of them of pluggable type. A pluggable ROM stores a plurality of programs and comprises a portion formed of an associated plurality of registers each one storing a jump instruction and the associated programs. The numerical addresses of said registers are represented by a series of numerals which can be entered by the keyboard. Programs can be entered from the numerical keyboard into a RAM memory, in form of a sequence of numerical codes, each code corresponding to a subroutine prerecorded in a ROM. Each program so 'learned' by the computer can be repeatedly executed by depressing a fixed code on the keyboard.
