i thought its a space If you are not sure what it is then you could try to find out with something like this. `$ perl -e ' > $string = qq{P\0A\0T\0C\0H\0I\0N\0S\0T\0}; > printf( qq{0x%02x: %s\n}, ord, $_ ) for split m{}, $string;' 0x50: P 0x00: 0x41: A 0x00: 0x54: T 0x00: 0x43: C 0x00: 0x48: H 0x00: 0x49: I 0x00: 0x4e: N 0x00: 0x53: S 0x00: 0x54: T 0x00: $` [download] I hope this is of use.

If you are really sure that this is what you want to do, why use a regexp? You could remove it using tr//d. If you fancy regexps, s/\0//g should do the job. -- Ronald Fischer <ynnor@mm.st>	[reply] [d/l]
