What are these doing?
Just a quick question...

Messing around with a script and this is present:

$VALUE{'MESSAGE'} =~ tr/\$\\\`\+\<\>\/\;\|/_/;

$VALUE{'MESSAGE'} =~ s/\r//g;

I think the first one is removing potentialy harmful characters from an input (via the form) but what is the second one doing?

The second one is changing \r (enter, or return values) into blanks. For example;

this
is
a
test

would be changed to;

thisisatest

At least thats what I think. I'm not totally definate what \r means Tongue
