That is truly scary isn't it.

RPG isn't consistent though. Both DSPLYs are done in this program, so
it's both false and true.

Many languages specifically define that 0 is false and anything else is
true. But for RPG, it's undefined what will happen if an indicator
doesn't have the value '0' or '1'.
With RPG, since it's undefined behaviour, the compiler is free to
generate code to compare the indicator to either '0' or '1' depending on
which makes more sense for that specific case.
