Re^2: [OT]: missing character when reading input file

I agree with your example of using open to handle a CRLFish file on a *nix system. The rest of this post is just to satisfy my curiosity.

$ARGV[0] = \do{$win_file};

I don't understand the purpose of munging @ARGV in this way. Any scalar can be opened by reference as a RAM file. If the reason for initializing the scalar in a BEGIN block was to create a lexically private scalar, then assigning a reference to it to an element of the global @ARGV array defeats this purpose.

Give a man a fish: <%-{-{-{-<

The array @ARGV was used to preserve as much of the original OP as possible. The 'BEGIN' is unnecessary, but I feel that it serves to separate the file simulation from the relevant code. No excuse for the 'do' block. It is a leftover from an earlier attempt at the file simulation. Bill	[reply]

The array @ARGV was used to preserve as much of the original OP as possible. Ah, ok. I understand better now. It occurred to me after I posted that this might have been part of the motivation. Give a man a fish: `<%-{-{-{-<`	[reply] [d/l]
