21.5 Draw
VISSCREEN (Statement)
Function
Designates a drawing screen.
Format
VISSCREEN <Draw object>, <Screen number>[, <Draw mode>]
Explanation
<Draw object> Designates the storage memory or overlay memory
(screen) (0 or 1).
0: Storage memory (Processing screen)
1: Overlay memory (Draw only screen)
<Screen number> Screen number on each screen
Storage memory (Processing screen): 4 screens from 0
to 3
Overlay memory (Draw only screen): 2 screens, 0 and
1.
<Draw mode> Designates the display drawing method(0 or 1).
0: Instant display OFF
1: Instant display ON
If ignored, 1 is the default setting.
Note (1): When you turn ON the power, VISSCREEN 1, 0, 1 are set as
the initial setting.
Note (2): When the system executes the draw instruction with instant
display ON, the draw result is displayed on the monitor.
However, with instant display OFF, the screen is renewed
after the execution of instructions corresponding to the draw
object of either VISPLNOUT or VISOVERLAY.
Note (3): With instant draw ON, when the draw instruction is executed,
it takes about 0.02 seconds for the system to renew.
Therefore, if you frequently repeat drawing, requirement time
rapidly accumulates. By setting the instant draw to OFF and
displaying all objects once, it is possible to save processing
time.
Note (4): For this instruction, a µ
µµ
µVision board (option) is required.
