Hey, Shelbi,  we do something like that here for a PACS system that doesn’t like lines greater than 70 characters.  Here’s the xlt proc we use.  I’m sure there’s a more elegant way to do it, but it works for us.  It splits the field on a space character, then builds lines word by word until it reaches the max line length(which you’d need to change).  If adding a word to the line exceeds the max line length, it starts a new line.
HTH,
