When you start Microsoft CodeView under Windows 3.00 in a 386 enhanced
mode DOS box, the following error message is displayed:
You have attempted to run 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 to tell CodeView that
expanded memory is available, as follows:
CV /E
This information applies to Microsoft CodeView versions 2.35, 3.00,
and 3.10 for MS-DOS.
Note that CodeView version 2.35 is shipped with Microsoft BASIC
Professional Development System (PDS) version 7.00; CodeView version
3.00 is shipped with Microsoft C Compiler PDS version 6.00; and
CodeView 3.10 is shipped with Microsoft BASIC PDS version 7.10.
You may find that after the error message is generated, if you return
to the DOS box and wait a few seconds, CodeView will 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 3.00
DOS box in standard mode, WIN /S.
