cool, but why doesn't my @ftapes = system ("evmvol -w label_state=3|grep barcode"); print $ftapes[0]
OR print $ftapes[0,1]
work?
Because system() does not return the program's output, it returns exit status.
I see that it does not support multidimensional arrays, so how do I implement this using system?
Multi-dimensional arrays are possible in Perl, with references. If you want to talk about that, please send a new message asking your questions about that topic.
You don't do what you show with system() because that's not what it's for. Backticks fill that role.
