Great Tip from Ken Ray about lineOffset

[Chipp Walters]

Chatting w/ Ken Ray tonight, he shared a really cool tip...one I didn't 
know.

The lineOffset function returns the line number of the first occurence 
of a matching string.

So if you have a list tList:

A,apple
B,bacon
C,carrot

And you use

put lineOffset("C",tList)

it will return '2' because 'c' is in 'bacon' and that's on line 2.

Of course what we want is to find the first occurence of a line STARTING 
with 'C'. Many of you know that lineOffset doesn't work with regular 
expressions.

So doing something like:

put lineOffset("C*",tList) won't work.

But, it turns out this will do the job!

put lineOffset(cr & "C",cr & tList)

The first cr makes sure the line you're looking for starts with 'C' and 
the second one is used to 'sync' up the number you're returning.

Thanks Ken!
