Compilation continues but no compiled source code file will be saved.
A pattern variable can be accessed in an another
subpattern, a '%x' format item, or a pattern test only if some
text has been saved into that variable. Also, the pattern variable
access must appear in the same rule in which it was saved, if it was
saved in a find or translate rule. If the text was saved
in the pattern part of a match alternative of a DO SCAN or
REPEAT SCAN action, the pattern variable access may appear only
within that same match alternative. It becomes unspecified at the
end of such a match alternative.
