Abstract

A method is described to permit an operator of an interactive information handling system to key new graphic symbols into the system from the keyboard which the operator has previously defined. New technology printers and displays employ very large character sets, known as code pages. Two of these code pages are generally required: Code Page 256 (American and Western European characters) and Code Page 259 (technical symbols). These character sets are up to 190 characters large. Previous character sets employed in the prior art have been based on printers which could support 88 characters or 96 characters. The IBM Displaywriter text processing program supported Code Page 256 on the IBM Personal Computer through a series of different predefined keyboards known as "home keyboards.
