Re^2: Length of unpacked string for "hex" data

Thanks, very cool. And I like the dispatch table trick as well; seems I have another app where that will be useful. For the present case I'll stick with your "if"; it's less intrusive than mine.

I noticed you used a lower-case "a" in the template:

"A2C/a"

Meaning to parse on a null-padded string rather than a space-padded one. Is that important here?

'A' will remove trailing NULs and whitespace. 'a' will not. In other words, `($str) = unpack('c/A', $data);` is equivalent to `($str) = unpack('c/a', $data);` `$str =~ s/[\0\s]+$//;`	[reply] [d/l] [select]
