This utility function makes the mouse cursor visible on the monitor.
When RM/Panels opens a panel library, it checks for the presence of a mouse. If a mouse if found, the mouse cursor is displayed. This mouse cursor remains visible until you remove it with the HIDE MOUSE CURSOR utility function. After hiding the mouse cursor, you can use the SHOW MOUSE CURSOR utility function to make the mouse cursor visible again.
When the RM/Panels runtime system opens a panel library, it automatically makes the mouse cursor visible if it recognizes the mouse. The SHOW MOUSE CURSOR utility function is only needed if you hide the mouse cursor and then want to restore it.
