in thread How to get string from array from module?

I don't see the point of turning @SELECTED_COLOR into a reference and then back again. Why not simply do this:

### NOT NEEDED my $SELECTED_COLOR; ### NOT NEEDED $SELECTED_COLOR =\@SELECTED_COLOR; glColor4f (@SELECTED_COLOR, $volume->color->[3]);

    Well ... if that was your second day with Perl; everything seems so ... you know! :-) You're absolutely correct - of course! Thanks for the hint!

      Sorry - didn't mean it to sound critical. As the post I replied to just showed some lines in isolation it could well have been the case that there was some benefit to using the reference which we might not have known of. I could (as usual) have phrased it better.

      And if it is only your second day and you are handling stuff like this so well then you will go a long, long way.
