I've had some success at using Codeview with MSC 6.0 to debug GEM
applications, but I still have a few problems.

The development system is a 4M 386 with VGA and monochrome displays. The
software being developed is in a directory of its own. Codeview has been
renamed to .APP, and installed in the \GEMAPPS\GEMSYS directory. It is also
necessary to place a copy of the test application's resource file in the
\GEMAPPS\GEMSYS directory, but the application program, and the source
files, are all resident in the development directory. The following batch
file puts the target software on the VGA, and the Codeview display on the
monochrome display:

@echo off
what ye
set drive=%what%:
what y
set cpath=%what%
if %cpath% == "\" set cwd=%drive%%cpath%
if not %cpath% == "\" set cwd=%drive%%cpath%\
d:
cd \gemapps\gemsys
gemvdi cv /M /2 /X %cwd%%1.app
%drive%
cd %cpath%
echo on

The program "what" places the current drive and path into the environment
variable "what", for access by the batch file. The only problem with this
script is that the mouse is limited to the top half of the screen.

This batch file uses the VGA as the Codeview display, and the monochrome
display as the GEM screen (assuming the current system configuration is
for GEM on the monochrome display):

@echo off
what ye
set drive=%what%:
what y
set cpath=%what%
if %cpath% == "\" set cwd=%drive%%cpath%
if not %cpath% == "\" set cwd=%drive%%cpath%\
d:
cd \gemapps\gemsys
gemvdi cv /50 /F /M /X %cwd%%1.app
%drive%
cd %cpath%
echo on

Again, the mouse range is the top half of the screen only. When the target
program is running, the VGA is in graphic mode, and unreadable. The Codeview
display is constantly being redrawn, and is quite slow. At the exit from
Codeview, the GEM desktop display is redrawn on the monochrome screen, then
the system locks up.

Any help anyone can offer will be greatly appreciated.
