RETURN
Function: Return From Subroutine Jump/End Main Program
Type: Motion program (PROG only)
Syntax: RETURN
RET
The RETURN command tells the motion program to jump back to the routine that called the execution of
this routine. If this routine was started from an on-line command (RUN), program execution stops and the
program pointer is reset to the top of this motion program – control is returned to the Turbo PMAC
operating system.
If this routine was started from a GOSUB, CALL, G, M, T, or D command in a motion program, program
execution jumps back to the command immediately following the calling command.
When the CLOSE command is sent to end the entry into a motion program buffer, Turbo PMAC
automatically appends a RETURN command to the end of that program. When the OPEN command is
sent to an existing motion program buffer, the final RETURN command is automatically removed.
Examples:
OPEN PROG 1 CLEAR
X20 F10
X0
CLOSE ; Turbo PMAC places a RETURN here
OPEN PROG 1000 CLEAR
N0 RAPID RETURN ; Execution jumps back after one-line routine
N1000 LINEAR RETURN ; Ditto
N2000 CIRCLE1 RETURN ; Ditto
...
CLOSE ; Turbo PMAC places a RETURN here
