Displayer Script

== Overcomplicated C-c-c-c-ombo breaker. ==
I went ahead and way over complicated this script, but allows for a lot more functionality.
You can use way more than seven lines. 
llSetText is always limited to 254 bytes and will be truncated as such. Be weary of this when using this script.
Essentially unlimited lines (until script memory runs out) is irrelevant due to SetText limits. 
Whatever, enjoy. -- User:Niles Argus

This is a simple 7 line displayer script that is easy to use and if you ask me very useful
