Re: simple to describe I/O problem

In addition to the above, your arguments to open are wrong, see IO::File. Try this instead:

...
my $fh=IO::File->new;
if ($fh->open("$file","<")) {
...

`if ($fh->open("$file","<")) { ... }` Why does the string `$file` have to be interpolated into another string `"$file"` before being passed to the `open` method?	[reply] [d/l] [select]

It doesn't, `"$file"` was just a remnant of (too) quickly editing the OP's code. (Unless maybe `$file` is an object with overloaded stringification; but then it'd probably be stringified inside `open`...)	[reply] [d/l] [select]

Thank you. My bad, it was a trivial mistake, it works now :)	[reply]
