SECTION 12 USER TASK
Example 2: Main Program
LE33013R0301400320003
When block N1000 in the main program is executed, sequence execution jumps to subprogram
O1234.
The subprogram is executed from N001 and when the control reads the RTS
statement in N050,
sequence execution then jumps back to N1001 of the main program and the commands in that block
and subsequent blocks are executed. At the same time as the jump from the subprogram to the
main program occurs, variables XP1 and ZP1 are cleared.
Order of program execution:

[Function]
The designated subprogram is called each time an axis motion command is executed. That is, the
