Just to be pedantic, RPG is documented as using "short circuit expressions", so
it can be relied upon to act the way you described.  And while the same is true
of C, C++, and Java, it is not necessarily true of all languages.   That can
make things like:

  If index > 0 and array( index ) = "foobar" ..

fail with an array index error when "index" is 0 because without short
circuiting, it would still attempt to validate the second half. Thankfully RPG
does use short circuit expressions though...
