Re^2: Compare two files, nested while loops? Outer loop not iterating?

[naturalsciences]

So in effect my original script would have a workflow like that > Iterate outer loop (QA lines)..first iteration.. along comes the inner loop (FA lines) > iterate wildly through it to the EOF, evaluating "if condition" if (hehe) it happens somewhere in the FA. Now should come the next iteration but FA is already read through, so no more lines from QA will ever be matched to anything.
