RET subprogram return

Function
The RET command can also be used in the subprogram as a substitute for the M17 return
jump command. RET must be programmed in a separate part program block. Like M17, RET
prompts the return to the calling program at the part program block following the subprogram
call.
Note
Parameters can be programmed to change the return jump behavior of RET (see
"Parameterizable subprogram return jump (RET ...) (Page 195)").
Application
The RET operation should then be used if a G64 continuous-path mode (G641 to G645) is
not to be interrupted by the return.
Condition
A condition for using RET is that the subprogram does not have a SAVE attribute.
Syntax
PROC <program name>
...
RET

Comment
; Return jump without interruption of continuous-
path mode.
