摘要
A program selector in an electronic calculator has a number of formulas which are printed in human readable form. When a formula is selected by the operator a machine readable representation of the formula is positioned adjacent a transducer. The transducer generates an electrical signal which represents an identification of the particular mathematical formula or other type of program to be executed by the electronic calculator. The electrical signal is decoded by a decoder which generates a storage address for the starting point of the formula or program to be executed.
