How does the vbs host script keep the displayed black window from disappearing automatically?

test.vbs file statement:
wscript.echo "hello world"
wscript.sleep 2000
double-click the vbs file to execute. If you don"t add sleep, the black window just disappears, and if you add sleep, you only stay for 2 seconds. How do I make the black window not disappear automatically and then disappear after I click on the closed X?
