I took your suggestion of a flag, and after wrestling with it for a few hours, came up with this:
It works, and it works reliably, but there's one thing I don't like about it.
If I'm following it correctly, (and I'm pretty sure I am) the flag blank carries a 1 as soon as a single blank is encountered.
That is, if you ran it on this sentence, the space between "That" and "is" would set blank to one, and it would be one until it was re-set, and it wouldn't be re-set until the word "if".
So it would work, it wold do its assigned task correctly, and the code would use the first else if when it didn't have a blank set, and the second else if when it did.
So my only gripe is that the flag blank isn't reliable-- it does not show the truth about whether the first blank has been encountered at all times.
On the other hand, when I swore at it, I woke my wife up, so I think I'll put it away for tonight.

I want to insert "Text" in each file as a place where I mentioned below "Insert Text Here". These files are something like news of newspaper. Generally, newspaper headlines contain one or two lines.
