Okay, now I see the difference between list and scalar context...I thought the whole section on the range operator referred to it in list context(and I tried to make sure that I
carefully read the docs...DOH!). It is definitely more clear now.
Still a bit confused though. After re-reading, I tried a few more examples. The goal of each is to print the numbers 5,6,7,8,9,10, one to a line.
@arr = (1 .. 20);
foreach $i ( 0 .. $#arr ) {
if ( $i == (5 .. 10) ) {
print "$i\n";
}
}
# output was "0\n"
@arr = (1 .. 20);
foreach $i ( 0 .. $#arr ) {
if ( $i == 5 .. 10 ) {
print "$i\n";
}
}
# output was 5-19, one integer to a line
@arr = (1 .. 20);
foreach $i ( 0 .. $#arr ) {
if ( $i = (5 .. 10) ) {
print "$i\n";
}
}
# no output - '$i = (5 .. 10)' never evaluated true
Maybe I am misunderstanding how to use the operator is scalar context. The examples in the docs don't really help. Of all the examples listed, I thought the first was going to work. I'm really not understanding why it didn't.
Thanks for your help to this point.
