Sure is. First of, your line with $LIST = "AF00001" won't work, because =
is for assignment, not testing for equality. You want to use eq (use ==
for numerical values only. You should also avoid using all caps for
variables -- use all caps for constants or filehandles. This is a style
thing.
Here's how I would code this:
foreach (@mylist) {
$boolean = ($_ eq 'AF00001') ? 1 : 0;
}
The conditional operator, ?:, tests an expression, and returns the first
value if the test is true, and the second if the test is false.
