Hi, I have a few questions about MSC 5.1 and codeview.

1. In the Runtime Library Reference, there is a list of functions
   that is supported in real mode only.
   e.g. _dos_findfirst, _dos_getdrive ...
   Where can I find the description of those functions,
   i.e. parameters, calling conventions, return codes etc.

2. How do I trace a program with overlays? Can I trace into an overlay??

3. I tried to use cv (codeview) on a program but got a message:
   not enough space. Then I set up some expand memory (as suggested
   by the MSC manual) and used cv /E but I still got the same error.
   Is there any other way I can trace "large" programs. Source code
   for that program is not available so I cannot recompile.

My machine is a Model 70 (16 MHz) with DOS 4.0.

Thanks a lot.
