Re: [SLUG] perl substitution of metacharacter

[Russell Davies <russell.davies@xxxxxxxxxxxxx>]

; garfield:~# ascii ^@
; ASCII 0/0 is decimal 000, hex 00, octal 000, bits 00000000: called ^@, NUL
; Official name: Null
; 
;      So it's just a null so something like
; 
; print $c unless ($c = 0);

no, that's wrong.

-	you're assigning not comparing.
-	what are you comparing? (what happens if you get a '0' in your
	input, or if you've converted to ascii value first, why are you
	printing this value and not the character itself?)
- 	this construct will yield poorer performance than a regexp.
