cool, but why doesn't
my @ftapes = system ("evmvol -w label_state=3|grep barcode");
print $ftapes[0]
OR
print $ftapes[0,1]
work?
I see that it does not support multidimensional arrays, so how do I
implement this using system?

To capture output you need the backticks
my @output = `put your command here`;
The return value of a system call is the return value of the program you
call.
See perldoc perlfaq8 for more info

Subject: array population from system app call
All,
was hoping anyone could provide some syntax help.
I want to populate an array from a system app call like so.... and then
print out each element.
my @ftapes = system ("evmvol -w label_state=3|grep barcode");
print $ftapes[0]
or
print $ftapes[0,1]
The problem is it prints out all the lines for print $ftapes[0] and does
not print for print $ftapes[0,1]
OR
should I just run the system call, put it to a file
then open the file, read line by line
chomp
foreach $_
print $_
close file
thanks
