<p>PURPOSE:To grasp stored contents by displaying a program number and comments with respect to a command program, to which comments are added, in a numerical controller provided with a program list display function. CONSTITUTION:The command program obtained by reading a command tape by a tape reader 3 is stored in a memory 6, and the program number and the start address of the command program which is divided and stored in plural areas of the memory 6 are stored in a memory 7. When a keyboard 5 is operated to display a list of programs, a microprocessor 1 reads out the head address stored in the memory 7 and reads a prescribed number of head characters of the command program form the memory 6 on the basis of the read address. It is judged whether comments are added to the command program or not on the basis of read characters, and the program number of coments are displayed on a display device 2, and only the program number is displayed if comments are not added to it, thus judging stored contents.</p> |
