Re : updating text

When you only want to see the last line / temp var (in my code), show it via text() and don't use val.

That works together with background().

You can also choose a font and a fontsize and a color for the text.

text() also allows to define a rect that will not be exceeded even by too long text.

Hope this helps!

like this...

1. //String val="pwwe";
2. int j=0;
3. void setup()
4. {
5.   size(500, 500);
6.   frameRate(1);
7.   textSize(32);
8. }
9. void draw()
10. {
11.   background(111);
12.   //myPort.write("temp?");
13.   int  i=0;
14.   String temp="";
15.   while ( i < 10) {
16.     temp = temp+char(i+j+65) ;
17.     i++;
18.   }
19.   j++;
20.   // val = temp+"\n"+val;
21.   //println(val);
22.   if (temp != null && temp.length() > 0) {
23.     text(temp, 50, 100, 110, 200);
24.   }
25. }
