DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing an example of a numerical controller having a multiple program function of the present invention in correspondence with FIG. 5, and the same components are designated by the same reference numerals and the description thereof will be omitted.
A machining program is stored in the machining program memory 1, and the machining program is read from the machining program memory 1 for each block via the reading circuit 2 by an operator or the like instructing with an operation panel (not shown) such as a keyboard. The multiple program instruction selection circuit 3 for selecting the CALL instruction, the O instruction which is the program call instruction, and the RTS which is the return code is selected, and the multiple program instruction PC is selected by the memory write switching circuit 4 based on the CALL and RTS. The O command PC1 in the parent program and the O command PC2 in the child program are written and stored in the child program memory 5 and the grandchild program memory 6. The stored O commands PC1 and PC2 are read from the child program memory 5 and the grandchild program memory 6 by the multiple program list display circuit 7 and displayed on the CRT display device 8 as a list PTB.

Before describing the operation flow of the apparatus of the present invention, the flow of a machining program using a general multiple program will be described with reference to an example of the machining program shown in FIG. The machining program starts with the program name O1000 and ends with M02. The machining program is a command to call a child program, 'CALLO1100'.
And'CALL O1200 '. The child program starts with program names O1100 and O1200 and ends with RTS. Further child program O11
00 is a command to call the grandchild program, 'CALL
O1110 'and'CALL O1120' are included. The grandchild programs are program names O1110 and O1.
It starts at 120 and ends at RTS.

The programs are written in the order of the arrows shown in FIG.
Start from 1000 and proceed to the block "CALL O1100" (B1). Then from O1100, 'CALL
Proceed to block O1110 '(B2), then O11
Proceed to block 10 of RTS from 10 (B3), 'CAL
Return to the block next to LO1110 'and call'CALLO1
Proceed to block 120 '(B4). Then O1120
Go further to the RTS block (B5), 'CALL
Return to the block next to O1120 'and proceed to RTS (B
6). Then return to the next block of'CALL O1100 'and proceed to the block of'CALL O1200' (B
7). Next, the process proceeds from O1200 to the RTS block (B8), returns to the next block of'CALL O1200 ', proceeds to M02 (B9), and ends the operation.

FIG. 3 is a flow chart showing an example of the operation of the apparatus of the present invention. First, it is confirmed whether or not an operator or the like has input a multiple program list display command using an operation panel such as a keyboard (step S1), and then input. If not, the process proceeds to step S15. On the other hand, when the multiple program list display command is input in the judgment step S1,
In accordance with the operation order of
Read one block of machining program (step S
2) The multi-program command selection circuit 3 confirms whether there is a multi-program command in this block (step S3). If there is no multi-program command, step S1.
Go to 4.

On the other hand, if there is a multiple program command in the judgment step S3, the multiple program command selection circuit 3 checks whether the multiple program command is CALL (step S4). If it is CALL, the memory write counter variable " COUNT "is incremented by 1 (step S5), and step S
Proceed to 14. On the other hand, if the result is NO in the judgment step S4, the multiple program command selection circuit 3 confirms whether or not the multiple program command is RTS (step S6), and if it is RTS, the memory write counter variable "COUNT" is decremented by one. (Step S7), the process proceeds to step S14. On the other hand, if the result is NO in the judgment step S6, the multiple program command selection circuit 3 confirms whether or not the content of the memory write counter variable "COUNT" is 0 (step S8). The name is written in the parent program name area of the child program memory 5 (step S9), and the process proceeds to step S14.

On the other hand, if the decision step S8 is negative, the multiple program command selection circuit 3 confirms whether or not the content of the memory write counter variable "COUNT" is 1 (step S10), and if it is 1, the O command is issued. Is written in the child program memory 5 as a child program name (step S11),
It proceeds to step S14. On the other hand, if the result is NO in the judgment step S10, the multiple program command selection circuit 3 writes the O command as the grandchild program name in the grandchild program memory 6 (step S12), and the O command written at the end of the child program memory 5 is written. Is written in the grandchild program memory 6 as the callee program name (step S13). Next, the multiple program command selection circuit 3 confirms whether or not the reading of all blocks of the machining program has been completed (step S14), and if not completed, returns to step S2 and repeats the above operation.

On the other hand, when the reading is completed in the judgment step S14, the multiple program list display circuit 7 reads the contents of the child program memory 5 and the grandchild program memory 6 (step S15) to form a tree-like program name list. Display on the CRT display device 8 (step S1)
6). Here, FIG. 4 is a diagram showing an example of a multiple program list displayed on the CRT display device. In this embodiment, the case of one grandchild program memory has been described, but if the hierarchies of multiple programs are further increased, the grandchild program memory may be increased.
