hi,
when you want to get rid of newlines and carriage returns, is it correct to
use:
tr/\n&&\r//g; ?
below you suggested tr/\x0a\x0d//d;
what does "x0a" and "x0d" mean?
where can i get a list of all these strange characters and their meaning?
a few days ago, Bill suggested : tr/015d//g; to get rid of carriage returns;
i'm confused. pls. help.
thanks!

If the above is what you want, then use
tr:
$somestring =~ tr/0-9a-zA-Z//cd;

You can add it to the above 'keep' list (how about tabs?):
$somestring =~ tr/0-9a-zA-Z\x20\x09//cd;
Or you can figure out exactly what you DON'T want
and use something like (to get rid of newlines and
carriage returns):
$somestring =~ tr/\x0a\x0d//d;
HTH,
