I have a reference to an annonymous array, which I am looping through with foreach(@$servref) { if ( checkServer($_, $dn) ) { push(@$goodservref, $_); } else { # server wasn't good. Add another item to the list push(@$servref, newitem);

Re: for/foreach question

Hi, I think it is good to have foreach and for loop even tough they are the same if you are searching in a file you can almost make a sentence foreach $line(@infile) #<-- to me this is more readable than for $line(@infile) But for loop, I use it only for numbers for(1..53) or for( $i=0;$i<50;$i++)

for/foreach question

I just stumbled upon this in some perl I'm working on: for $arrayref (@datedbi) { #do stuff } It didn't look right and sure enough, it should be 'foreach'. But it worked fine and that's my question - why is this working? @datedbi's elements are references to lists and they all seem to be get

I am also a newbie, and I'm also currently on Chapter four of O'Reilly's Learning Perl. I just have a simple question about something I just read which confused me... In CH4, in the section on foreach loops, the book says, "If the list you are iterating over is made of real variables rather than
