Re: and this or that

And & or have the lowest priority possible, according to perlop, so you are safe. The last few from the row:

           nonassoc    list operators (rightward)
           right       not
           left        and
           left        or xor

You see, the list operator is even higher, and that is the most tricky one out there.

I wouldn't use and with substitution, though. Just:

s/test/somestuff/;
print;
[download]

does the job cleaner: only one print.

Hope this helps,

Thank you for the reply jeroenes. (BTW, the first block in my question has a mistake, saying "$_" where it should say "$next".) You said I wouldn't use and with substitution, though. Just: `s/test/somestuff/; print;` [download] does the job cleaner: only one print. You're right about that. Would the following be a better illustration of the advantage I perceive? `s/^(\d+)/("0"x(8-length).$1)/xe and print or s/^(\w)/("\x20"x(8-length).$1)/xe and print for @ARGV;` [download] Suppose that @ARGV is a combination of digits and words, all digits get zero-padding and all words are padded by space. Anything that fails both matches should be discarded. Update: Very well then, jeroenes - I will follow the tradition And thanks again for the replies :-) mkmcconn	[reply] [d/l] [select]

Even than: `for (@ARGV){ print if s/first/somet/ or s/second/somet/; }` [download] Would use only one print ;-). Jeroen "We are not alone"(FZ)	[reply] [d/l]
