TYPEWRITER TO BE CONTROLLED BY PROGRAM

摘要

PURPOSE:To detect a program error easily by printing out the number of lines and data of a program executed on the basis of the tracing operation of a program stored by a tracing command at the setting of a program control mode. CONSTITUTION:A variable area 60 storing an operated result at the setting of the program control mode is formed in a memory 53. When the tracing command is inputted on the basis of prescribed keying operation at the setting of the program control mode, a CPU50 reads out the program from a memory area 58 to execute the tracking operation of the program. The CPU50 makes a printing part 51 print out the number of lines of the program and data outputted by a printing output instruction in the program on printing paper and displays data outputted on the basis of a display output instruction in the program on a display device 10.
