This is one of those damned-if-you-do-damned-if-you-don't situations.
The yyerror() routine purposely does not exit after the first syntax
error in the hope that more (legitimate) errors will be discovered and
reported. This doesn't always work out.

You can edit the yyerror() routine in awkgram.y to call exit(EXIT_FAILURE)
at the end.  You could also just increase the history size of your terminal
emulator for scrolling backwards.

I don't particulary wish to add an option or environment variable
to change this behavior.

Thanks,

Arnold
