> This pig script: 
> -- REGISTER $unknown;
> x = LOAD 'nn' AS x:chararray;
> DUMP x;
> I run like this:
> > java -jar ../../../../Pig/pig.jar -x local -file nn.pig
> and pig does nothing, just exits without doiung anything.
> But if I remove the $ from the first line of the script, then:
> > java -jar ../../../../Pig/pig.jar -x local -file nn.pig

- 100% complete!
> 2009-02-13 16:30:01,063 [main] INFO  org.apache.pig.backend.local.executionengine.LocalPigLauncher
- Success!!
> (abc)
> (def)
> Similarly if I define the unknown parameter on the command line, it works fine:
> > java -jar ../../../../Pig/pig.jar -x local -file nn.pig -param unknown=1

- Success!!
> (abc)
> (def)
> It seems that undefined parameters cause pig to exit without doing anything... even if
they are within a comment...
