RET subprogram return

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 512)").
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 jump.
Requirement
The RET command can only be used in subprograms, which were not defined with the SAVE
attribute.
