Re: pushing a $variable into an array with varible name

It looks like you might want a hash of arrays.

@vol = ( "vol1", "vol2" );
$contextID = 9;
$datastream = "this is just a data stream test";
( $a, $b, $c, $d, $e, $f, $g ) = split /\s+/, $datastream;

my %hash;
$"=" "; #see 'perldoc perlvar' for what this means
push @{$hash{"$contextID-$vol[0]"}}, $a;
push @{$hash{"$contextID-$vol[0]"}}, $b;
print "output0: @{$hash{"$contextID-$vol[0]"}}\n";
push @{$hash{"$contextID-$vol[1]"}}, $a;
print "output1: @{{"$contextID-$vol[1]"}}\n";

You need double-quotes around those hash subscripts. We're not really tightening our belts, it just feels that way because we're getting fatter.	[reply]
