Having trouble with strings ...

[mlseim]

For the life of me, I just can't figure this out ...

Take this example:

$start = 1;
$end = 10;

for $list ($start..$end) {
$item="thing$list";
@$item=("zero","one","two","three");
}

I end up with 10 arrays ...
@thing1=("zero","one","two","three");
@thing2=("zero","one","two","three");
@thing3=("zero","one","two","three");

... etc ...

Now I want to print out one of the items in one array ...

$test=3;
print "Here's an item --- $thing$test[2] .... ";

See, I want to print out the item in array "thing3[2]"
I can't figure out how to represent "thing3[2]" in the
print statement, because the "3" is a variable ($test)

I want the print statement to look like this in the end:
Here's an item --- two ....

If I do this,
print "Here's an item --- $thing3[2] ... ";
It works OK.

I just can't make the "3" a variable.

@thing3=("zero","one","two","three");

$i = 3;
$name = "thing" . $i;
$item = $$name[2];
print "$item\n";


does that solve your problem?

Thankyou! That is it!!

I've programmed in VBasic, C++ ... why didn't I know
that I could use "$$" double dollar signs?
(slapping myself on my forehead)

That's why this forum is here ...

Thanks again for the help,

Note though that symbolic references is considered sloppy programming. You could trymy @thing;
$thing[$_] = [qw[zero one two three]] for 0 .. 9;

my $item = 3;
print "Here's at item --- $thing[$item][2]";
