' viewports. The CLS statement is used to clear the graphics viewport
' after 30 circles have been drawn and to clear the text viewport after
' "Hello" has been printed 45 times.
' To try this example:
' 1. Choose New Project from the File menu
' 2. Copy the code example below to the code window
' 3. Press F5 to run the example
CLS ' Clear the screen
RANDOMIZE TIMER
SCREEN 1
VIEW (5, 5)-(100, 80), 3, 1 ' Set up a graphics viewport with a border
VIEW PRINT 12 TO 24 ' Set up a text viewport
' Print a message on the screen outside
' the text viewport
LOCATE 25, 1: PRINT "Press any key to stop."
Count = 0
DO
' Draw a circle with a random radius
CIRCLE (50, 40), INT((35 - 4) * RND + 5), (Count MOD 4)
' Clear the graphics viewport every 30
' circles
IF (Count MOD 30) = 0 THEN CLS 1
PRINT "Hello. ";
' Clear the text viewport every 45 times
IF (Count MOD 45) = 0 THEN CLS 2
Count = Count + 1
