3: Functions and features Series 2600B System SourceMeter® Instrument
3-82 2600BS-901-01 Rev. C / August 2016
The following programming example illustrates how to prompt the user to press the EXIT (LOCAL)
key to abort the script, or any other key to continue it:
display.clear()
display.setcursor(1, 1)
display.settext("Press EXIT to Abort")
display.setcursor(2, 1)
display.settext("or any key to continue")
key = display.waitkey()
display.clear()
display.setcursor(1, 1)
if key == 75 then
display.settext("Test Aborted")
exit()
else
display.settext("Test Continuing")
end
The above code captures the key that is pressed by the operator. The key code value for the EXIT
(LOCAL) key is 75. If the EXIT (LOCAL) key is pressed, the script aborts. If any other key is pressed,
the script continues.
