Number of chars in a line limit?

[ron barber]

Greetings,

Is there a limit to the number of chars on a single line? Line means
words with spaces between them but no return.

I have been formatting some long text sections with no return and
those with >10,000 or so chars have some difficulty displaying in a
text field, especially at higher point sizes. Is there a limit and if
so, is there a way around the display problems?

Thanks
Ron
