Working people make mistakes, some people do
never make mistakes! I work to live,
my boss thinks I live to work!
Using the JL
instruction (sort of CASE instruction) u can make the fastes step

This methode has probaly a maximum cycletime of 25 STL
instructions!(STL code)
(Using the formula: 10 instructions + amount of steps (the CASE
statement) + the max. conditions between steps + the max. actions in a
step.)
