I want to test if "AF1" is in my list @mylist;
I did:
foreach $LIST (@mylist) {
if ($LIST = "AF1")
$boolean = 1;
else
$boolean = 0;
}
is there a more elegant way to do it?
many thanks
jennifer

One thing
When you compare strings use "eq" string comparition operator. Not "="

That depends on what you're using @mylist for. If you're simply using it to
check to see if an element is in the list, then use a hash instead.
If you're creating the list element - b
push @mylist, $w

I'd actually be surprised if that works...
let me point out a few things:
if ($list = 'foo') will always be true.. you are assigning 'foo' to $list
what you want is probably 'eq'
the if block also needs curly brackets {} around it, especially if you want
to use the 'else' part
more so, assumign

sorry, incorrect sample. should be:
$boolean = grep /^AF1$/,@mylist;
with first regexp you catch every string, that contain 'AF1'.
