The S, T, and M functions that are used as the cutting conditions for the execution
of the G79 (G94, G24) cycle should be specified in blocks preceding the G79 (G94,
G24) block. However, if these functions are specified in a block independently wi-
thout axis movement commands, such designation is valid if the block is specified
in the G79 (G94, G24) mode range.
If the G79 (G94, G24) cycle is executed with the single block function ON, the cycle
is not interrupted halfway but it stops after the completion of the cycle consisting of
sequence 1 to 4.
