Assigning 2 arrays to scalar

Dente has asked for the wisdom of the Perl Monks concerning the following question:

I would like to know if it was possible to assign 2 arrays - @skeyw and @skeyw2 - to the same scalar so that both arrays contain the same information.

(@common) = split(/ /,$fields{'keywords'});
[download]

into perhaps

(@common, @common2) = split(/ /,$fields{'keywords'});

Your title is a little misleading, I think. Your idea will assign everything in the split list to @common and leave @common2 empty. Here, this does what I think you want, `@common2 = @common = split ' ', $fields{'keywords'};` I changed the split to magic split, just in case. If you're right about there just being one space in all cases, there is no harm done. After Compline, Zaxo	[reply] [d/l]

Your title is very misleading - please consider changing it. split returns an array, not a scalar. You can evaluate it in a scalar context if you like, but that's probably not your goal, according to the code you present (@ is for arrays).	[reply]
