FLIP


Flip the back buffer to screen and wait for next frame. This call is not needed when there is a _DRAW() or _UPDATE() callback defined, as the flip is performed automatically. But when using a custom main loop, a call to FLIP is normally needed:

::_::
CLS()
FOR I=1,100 DO
  A=I/50 - T()
  X=64+COS(A)*I
  Y=64+SIN(A)*I
  CIRCFILL(X,Y,1,8+(I/4)%8)
END
FLIP()GOTO _

If your program does not call FLIP before a frame is up, and a _DRAW() callback is not in progress, the current contents of the back buffer are copied to screen.
