MS-DOS
Summary:
With all versions of real-mode CodeView (CV) prior to version 3.0, the
mouse cursor does not display when running in a DOS session under OS/2
in the DOS compatibility box.
The situation exists because the mouse draws the pointer only in video
page zero, while CodeView uses video page one. This problem is caused
by OS/2 itself because the mouse cursor works normally under DOS.
To work around this limitation with CodeView versions 1.x and 2.x,
invoke CodeView with the /S switch so screen swapping is used as the
method of screen exchange. This method forces CodeView to swap in and
out of page zero.
Beginning with version 3.0, CodeView detects whether it is running in
a DOS session under OS/2, and if so, automatically starts up with /S
as the default in order to make the mouse visible.
