A specified G code for the condition applies for
assessment of the condition as well as for the
action if there is no separate G code specified for the
action.
Only one G code of the G code group may be
programmed for each condition part.
Programming example
WHENEVER $AA_IM[X] > 10.5*SIN(45) DO ...
WHENEVER $AA_IM[X] > $AA_IM[X1] DO ...
WHENEVER ($A_IN[1]==1) OR ($A_IN[3]==0) DO
...
