I think I read the following.

Is $row[-1] the same then $#row??

I tried it without success!

mmcw,

- $row[-1] means the value of the last element in the arrar @row.
- $#row means the last element number of the array @row.

Hence :

print $row[-1];

and

print $row[$#row];

would give the same result.

Hope this helps.
:-)
