If the digital signal NEXT1 is HIGH, the program will continue in line X. If the digital signal NEXT1 is
LOW, the program will continue in line Y.
An unconditional program jump (e.g. for infinite loops) can be generated by stating the same branch
destination for NEXT1=HIGH and NEXT1=LOW.
In Figure 23, the level test of NEXT1/2 is performed immediately at the start of program step 11. The
line of the next course program command is determined depending on the result of this level test.
