Sample block
N10 G10 X1000 F100 M10
N20 X2000 F500
N10 G10 X 1000 F100 M00

Effect
Blocks are treated as a single
block. No interruption takes
place.
Blocks are executed separately.
The program is interrupted
immediately preceding the
X2000 function.
The program is not aborted un-
til function G56 has executed,
i. e. just prior to the new posi-
tioning operation.
