Summary:
When you start Microsoft CodeView under Windows 3.0 in a 386
enhanced-mode DOS box, the following error message is displayed:
You have attempted to run a protected-mode application under 386
enhanced mode. To run the application, exit and run Windows using
either the WIN /s or the WIN /r command.
However, using WIN /s or /r is unnecessary. To avoid the error
message, start CodeView with the /E option, as follows, to tell
CodeView that expanded memory is available:
CV /E
This information applies to Microsoft CodeView versions 2.35, 3.0,
3.1, 3.11, and 3.14 for MS-DOS.
More Information:
After the error message is generated, if you return to the DOS box and
wait a few seconds, CodeView may start up. To avoid the error message,
start CodeView as follows with the expanded memory (/E) switch (where
<filename.exe> is the name of the program you want to debug):
CV /E <filename.exe>
To increase the size of programs that can be loaded into CodeView in
conjunction with the /E switch, you can create a PIF file for CodeView
and specify -1 for the expanded memory KB Limit, which instructs
Windows to give the program all the EMS that it needs.
CodeView will run without the above error message in a Windows 3.0 DOS
box in standard mode (WIN /S).
