(MCALL (expression), (assignment instruction), (assignment instruction),...) )
By means of the mnemonic MCALL, any user-defined subroutine (SUB integer) acquires the
category of canned cycle.
The execution of this mnemonic is the same as the mnemonic PCALL, but the call is modal, i.e.,
if another block with axis movement is programmed at the end of this block, after this movement,
the subroutine indicated will be executed and with the same call parameters.
If, when a modal subroutine is selected, a movement block with a number of repetitions is executed,
for example X10 N3, the CNC will execute the movement only once (X10) and after the modal
subroutine, as many times as the number of repetitions indicates.
Should block repetitions be chosen, the first execution of the modal subroutine will be made with
updated call parameters, but not for the remaining times, which will be executed with the values
which these parameters have at that time.
If, when a subroutine is selected as modal, a block containing the MCALL mnemonic is executed,
the present subroutine will lose its modal quality and the new subroutine selected will be changed
to modal.
(MDOFF)
The MDOFF instruction indicates that the mode assumed by a subroutine with the MCALL
instruction or a part-program with MEXEC ends in that block.
The use of modal subroutines simplifies programming.
Programming example.
The X axis is programmed in diameter.
