<CFSCRIPT>
string = "this is a test of of the emergency broadcast system. It is only a
test. If you expect this to go on and on, you are correct.";
cut=REReplace(string, '(.{1,24} )', '\1|','all');
</CFSCRIPT>
Your string is now cut up into a list. Each list element (delimited by a pipe)
is at most 25 characters long and ends in a space. Using a loop over the list
will allow you to put each slice into the DB.
Is this basically what you wanted?
