Re^2: Naming file handles with variables?

Should that be [$filename] here?

for my $filename (@fileNames) {
    open $fileHandles[$filename], '<', $filename or die "Can't open $f
+ilename: $!";

I don't thinks so. `open $fileHandles[@fileHandles], ...` 'creates' a new array element for the new file handle. You could instead: `open my $newFileHandle, ...; push @fileHandles, $newFileHandle;` [download] to achieve the same effect. If fileHandles were a hash instead of an array then keying by the file name would be appropriate however. True laziness is hard work	[reply] [d/l] [select]

OIC. Scalar context giving the next index. Hadn't seen this before, but it's interesting. I don't think I would use this myself, as I don't know who would be maintaining my code. I'd prefer the alternative you gave for transparency. Doubly preferred, given the OP's apparent sophistication level. -QM -- Quantum Mechanics: The dreams stuff is made of	[reply]

I agree with you. I probably should have used the less esoteric version given the OP's demonstrated level of expertise. However, you now know a new technique, so maybe pushing the edge of the envelope a little was the right thing after all. ;) True laziness is hard work	[reply]
