Subject: strange behaviour when sourcing inside function
In-Reply-To: <8D2E5359-D699-46AF-8FBA-8374FB3C7544@gmail.com>
Thanks for your reply! You may be correct, but the documentation of
"source" reads as whether the opposite is the case regarding the use of
TRUE and FALSE, doesn't it?
Your interpretation may be correct (it would be also in line with my
inutive interpretation of the combination of the word local and the
corresponding boolean values) but if it is, the manual (to me) is
misleading.
Cheers
