Re: Trying to get NULL with use strict; - How???

[Chris Anderson]

This, too, failed to give me what I wanted...

Here is the results I was given in the file:
Summary:
    1
Reproducible:
    2

Steps to Reproduce:
     1) 3
     2) 4
     3) 5
     4)
     5)
     6)
     7)
     8)
     9)
    10)
    11)
    12)
    13)
    14)
    15)
    16)
    17)
    18)
    19)
On the SCREEN, however, it has always worked properly...
Summary:
    1
Reproducible:
    2

Steps to Reproduce:
     1) 3
     2) 4
     3) 5

If there are no more Items, I want the loop to exit....

:)

Thanks!
