CVVERSION                     Set version of CodeView information to use 
------------------------------------------------------------------------------

 Purpose  : Set the version of CodeView information to use

 Syntax   : CVVERSION <0 | 1 | 2 | 5>

 Default  : 0

 The CVVERSION sets the version of CodeView information written to the .EXE
 file created by Blinker. The CodeView information version number does not
 refer to the version number of the CodeView debugger program, but rather the
 version number of the CodeView information format. At the time of writing,
 there are four possible versions, 0, 1, 2 or 5:

    0  All versions of the CodeView debugger through version 2.2
    1  The version of CodeView shipped with MS BASIC PDS 7.0
    2  The version of CodeView shipped with MS C 6.0
    5  The version of CodeView shipped with MS C/C++ 7.0, MS Visual
       C++ and MS Visual Basic for DOS 1.0

 Blinker defaults to producing executables which use CodeView information
 format 0.

 If you instruct Blinker to produce an executable to a lower version number
 than the version your CodeView debugger supports, some debugger features may
 not function correctly. Use the highest version number compatible with your
 debugger.

 Note: When using CodeView information version 5, please ensure Microsoft's
 CVPACK utility is in the path.
