Line spacing and Tabe size ?

I’m trying these functions but nothing happens if I modify it

I can’t write in two several lines!

and what is a Tab?

Thanks! (sorry for the english :frowning: )

Ok I can write in two several lines copyng and pasting a two lines text from a notepad file! But I still don’t understand the TAB SIZE option! what is it?

What functions are you asking about? Where are you trying to write these lines? What tab size option? Sorry, a little lost…

in a GUItext we have the TABSIZE option! what is it? what is a tab?

Tabsize is how many characters the tab character (\t) uses…
