Reply To: Add line break after 300 characters?

Caspian, I think I see what is going on. To Indesign, anything between spaces is one word, and with hyphenation turned off, it doesn’t know how to break the line.
But it looks like a few punctuation marks — period, underscore, right curly bracket, close paren — allow for a line break. (See line endings in your example on the left.)

I’m not a programmer, so I’m not sure how to tell it to count 300 characters, but I believe that if you could count to 300 and then put a discretionary line break it will do the same thing. Or just a manual return, I guess.

Normally I would say that one shouldn’t justify monospaced type, but if you have the EXACT number of characters in each line, it looks like it retains the vertical alignment:
