Re: Testing a string for a range of characters

In addition, if you're really worried this much about performance, your hash creation could be simplified:

my %hash;
@hash{'A'..'Z'} = ();

...

if (exists $hash{$whatever}) { ... }

Aha! That's what tilly had suggested, but without the `my %hash;` first, and I was getting confused when trying to combine the my and assignment in the same statment! Thanks Fastolfe, I'd not seen that particular usage before :-) As regards your other reply, currently I'm `shift`ing off the first element of the array, which tells me what the record type is. I then join the array with a delimiter for writing out to a flat file, minus the transaction type (or rather the transaction type get's built into the key I insert with the join).
