Hi All,
I use subs like ducks use water. It is about time
I learned what to properly call them.
I come from Modula2 and Pascal (as well as bash), "functions"
return a value outside the declared parameters and "(sub)routines"
only can modify values through the declarations parameters.
Sort of like
function: sub add($a, $b){return $a+$b}
routine: sub add($a, $b, rw $c){$c = $a+$b}
In Perl, what is the proper terminology?
Many thanks,
-T
I no longer use "rw $c". I always use "return".
The guys told me this was the best way on the
chat line, so I adopted it.
