Apparently when raising an error exception, Maple stops further code.

Is there any possibility to just show a popup message, and then continue with the code after the message?

Is there a way to get a feedback from Maple, if it doesn't find any corresponding proc: to a procedure call?

Right now it takes very much time to bugtrack issues where there might be a spelling error in a call.

See example.

Is there any possibility to modify column width within tables, so that they become equal?

Units are a neverending story, here's a variant of a problem raised before.

How can i get the minimum of 2 values with Units[Standard] loaded, when one of them could be zero (this loosing its units)?

I'm doing som XML readin, and need a bit help in using the HasChild function properly.

The attachment shows that using HasChild on a xmltree works fine, but I can't get i working when using it on a xmldocument. The latter is usually the case when you get when you read in from a file.
