The comments for rungs are similar to those for components except
that the syntax is a bit different. The rung comment syntax is:
RC: "comment" "more" "etc";
A rung comment must be followed by a rung.
The following tables lists each ladder instruction and its neutral text
format. For details about a specific instruction, see one of these
manuals:
