A key word can not be specified as a label.

JMP can be used for an upward jump.

STEP1 is taken as the jump label of JMP instruction in the program above. When Start changes to
TRUE, JMP instruction will jump to the position of STEP1 label and the program of network 3 will be
executed.
When
Start2 changes to TRUE, Out2 will also change to TRUE; the program of network 2 will not be
executed. When Start changes to FALSE, the programs from network 1 to network 3 will all be executed.
