Important Notice
The pages on this site contain documentation for very old MS-DOS software,
purely for historical purposes.
If you're looking for up-to-date documentation, particularly for programming,
you should not rely on the information found here, as it will be woefully
out of date.
Swap Video Pages (/S, /F) (CV only)
◄Up► ◄Contents► ◄Index► ◄Back►
────────────────────────────────────────────────────────────────────────────
In CV.EXE, the DOS or real-mode version of CodeView, the /S option
swaps the video pages used by CodeView and the application being
debugged. Use this option if
■ The application you are debugging uses video page 0, which
is normally used by CodeView.
■ You are unable to display the application screen during
debugging. This situation may arise when debugging
applications that run in graphics mode.
■ You are debugging with a mouse under OS/2 running in the DOS
session. If you are debugging under OS/2 running in the DOS
session without a mouse, you must specify the /M (Disable
Mouse) option when you start up CodeView.
See: ◄Disable Mouse /M►
The /43 and /50 options, which change video modes, automatically
select the /S option.
See: ◄Set 43-line mode (/43)►
◄Set 50-line mode (/50)►
The /F option does not swap video pages between CodeView and the
application being debugged. This option is the default for
CodeView, so you don't need to specify it explicitly.
The /F and /S options are not supported in CVP.EXE, the
protected-mode version of CodeView.
See: ◄Screen Swapping and Flipping►
