Larry Serflaten expressed precisely :

Just curious...
Why are you including the space in the collection of headings?

Shouldn't this
txt = Left$(txt, InStr(txt, " "))

be this?
txt = Left$(txt, InStr(txt, " ") - 1)

I did say 'for a quick example' ....

He was to define what a 'header' was. One of the rules might
be; "no trailing spaces" in which case he would have had to add
the code you supplied.

I saw there would be a trailing space, but as it did not effect the
listing I just decided to let it be. Having him in there adjusting the
code to suit his own needs would mean he pretty well understood
what was going on. That is the important part of coding....

if there is no space then the first example will return a zero-length string
and the second will raise an error. Depending on the input and the desired
results that needs to be considered.

Thanks Larry!
That's reasonable. It's just that his sample results list only includes
the first 'word' as there's nothing between the last character and the
linefeed.

I'm assuming your comment assumes txt is an empty string, in which case
I agree. In the case of Larry's code example, iteration of the list
doesn't leave txt an empty string.
