... which I didn't know I did, but now that I look at it I seem to have set:
echo $1: foo
echo $2: bar
So the question now is: why does ``set foo bar'' change $1 and $2 ? Is this
documented? If so, where ? More importantly, why? It renders the passing of
parameters to source'd scripts unusable, since you can't distinguish between
parameters that happen to come from the calling environment, and those passed
in as arguments from the the ``source script args'' invocation. Puzzled,
Philip
