Line 1,124: <br>If no subroutines have been invoked, then the '''RESULT''' special variable isn't defined. <br>If no SIGNAL or CALL (or subroutine invocation) has been used, then the '''SIGL''' special variable isn't defined. ~~<br>~~: (This excludes the use of '''SIGNAL ON xxx''' and/or '''SIGNAL OFF xxx''' instructions which don't actually transfer control).) In each case, the variable names may be in lower/upper/mixed case.
