This command closes the top window instance. As window instances are not automatically closed in Omnis, you can use this command to close the top window. No error occurs if there is no window open. This command clears the flag and does nothing if the top window is a private instance not belonging to the current task.
# Close the top window if it is called 'wMyWindow'
Ifsys(50)='wMyWindow'Close top window
End If
# Alternatively, use notation to close the top window
Do$topwind.$close()
