hiya monks,
I am printing a matrix of numbers out. I am using a hash structure with one key->array, ie. pushing in like this:

push @{$hash{$id}}, scalar @charcounts;

Problem 1: I want all the numbers to line up when printed out.

The values could be 1, 2 or 3 digit numbers. My script is a CGI, so Im guessing
I want to use printf qq(stuff here) but am not sure.

Problem 2: with one of the keys I must iterate over the multiple values in the
array separatley so I can set each of them as a hyperlink pointing to a different
page.I emptied the multiple values into a new array (dereferencing ?) like this:
@values=@{$hash{$id}};

Then I used a foreach to go through the array. I was surprised to find loads of extra whitespace
appearing. ie. I put into the values:1 2 3 4 5 6 etc. and out came:1(1 blank space)2(2 blank spaces)3(3 blank spaces).

Problem 3:I also have a problem (unless I turn strict off) when I try to print something for which there were
no values pushed in. I was hoping in these situtations just the key would be printed.

Any ideas?

thanks
