RE: Breaking text

["Joel Fritz" <JFritz@xxxxxxxxxxxxxxxx>]

The logic isn't too bad.  You need to break the source string into
tokens and read one token ahead while keeping count of the characters
before the peek ahead token. 

Read the source string until you find a space, keeping count of the
characters used.  Then peek ahead to the next space adding the number of
characters in the next token to your current count.  When you get to 25
or more fill the first field with <= 25 characters then put the
remainder, possibly including the peek ahead token, into the second
destination field. You probably will need more than 25 characters in the
second destination field.  Odds are the first field will break at fewer
than 25 characters. 

There are a couple of details about spaces I skipped to make it
clearer--you need to avoid starting line 2 with a space.  There's also
the possibility that there will be more than one space between tokens.
Be sure not to throw away any necessary spaces.

The infamous RPG Redbook has a nice example of using the C stream
tokenizer function.  It handles the whitespace problems for you without
your having to code them.
