Moin,

First advice: Use String.Len() (not Len) to measure the length of strings.

Second: In Linux, it is LF only, and as far as I understand, Windows 
seems to at least accept this too, meanwhile.

Then I send you a project of mine. It is a tool our students use to 
learn typewriting. There is a TextArea, and you can see how I managed to 
make it behave like a typewriter. Take a look at TextArea_KeyPress

This is not precisely what you are looking for, but maybe it can inspire 
your code.

Regards
Rolf
