IPC: G06F15/177
Filed: 1989-12-27
Abstract: PURPOSE: To make automatic selection of foreign language error messages possible by storing error messages in advance in an apparatus for arranging documents and putting them into envelopes. CONSTITUTION: Messages based on a plurality of languages are stored in an EPROM in a memory map. A pointer 506 is indexed to the first message to refer to an EPROM memory storing position region 501. Then, switching of languages is advanced to a judgement block 514 and in case where switching of languages exists, the pointer 506 is reset depending on the selected language. The system uses a concept of multiplier. The number of letters is determined by analyzing byte parts of the letters 501A to jump to a letter position 502A. When the number of jumps is equal to a multiplier for selection of letters, a program routine is returned to a start-up subroutine and when it is not equal, a jump counter is advanced by an increment by 1 and the program is returned to a block 518 and the action is repeated.
