TextArea_Lines --> Will always give something back with lines. For example TextAreaCursor(textarea,TEXTAREA_LINES)
will return the current line in which the cursor is. TextAreaCursor(textarea,TEXTAREA_CHARS) will return the correct Cursorposition related to the chars in the text.
So if you use TextAreaText with TEXTAREA_LINES and a length of 1 then the position means the line you want and TextAreaText will return the text of the desired line.
