PURPOSE:To shorten the time required for investigation of error causes, by checking freely each function information code for validity individually by a function check table. CONSTITUTION:A function analyzing part 9 analyzes the function information code cut out by a character taking-out part 7 and checks the information mode for validity on a basis of a check table 8; and if an error is detected, information indicating the existence of the error is written in an error information table 14, and the indication of information corresponding to the valid information code is stored in a function stack 10. The logical contradiction concerning the analysis result due to the analyzing part 9, the contradication in the course of updating of current information in an information setting part 11, and the contradiction on the character arrangement due to a character arranging part 13 are stored in the error information table 14. In this table 14, the position of the error information code or the error character code, the error classification, etc. are stored in correspondence with contradictions. |
