in thread Write to and read from scalar

GrandFather,

I did it this way from your example. I would not have known how to do this, but the disk file is basically a representation of the scalar. 

my $str = "Hello World\n";

open my $fIn, '<', \$str;
my $inStr = <$fIn>;
close $fIn;

print $inStr;

Is there a reason to use file I/O to the scalar?

Thank you

    For one use reread the OP's node. I frequently use the technique when answering SoPW's where an input file is required. I could write a temporary file then use that, but that adds clutter to the sample.

    In real applications I've used the technique to cache parts of a file that I need to access frequently and to provide a file handle for modules that require them when I really want to pass in a string.

    True laziness is hard work
