When compiling or assembling with the /Zi switch to include CodeView
symbolic information and linking with /CO to preserve it, the
placement of the /DO switch is crucial. If the /CO switch is specified
before /DO, the following behavior may occur when running CodeView:

   Message                                Behavior

   Enter directory for  (cr for none)?    When CodeView is executed,
                                          no source code will appear.

If switching the order of the /CO and the /DO switches does not
take care of the problem then you have to put the .DOSSEG into
your MASM routines and not use the /DO switch.

Microsoft has confirmed this to be a problem in Versions 3.65 and
5.01. We are researching this problem and will post new information as
it becomes available.

While LINK Version 5.01 may be used in OS/2, the /DO switch has no
meaning. Using it, however, causes the linker to GP fault if /CO
precedes /DO.
