I modified an old program with the new session type values,  and it seems
to work fine.  Note the new /dos and /doswin parameters:

 // msc 6
 #define INCL_NOPM
 #define INCL_DOS
 #define INCL_DOSERRORS
 #include 
 #include 
 #include 
 #include 
 #include 

 void showuse(void)
 {
    
printf("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX\n");
     printf("X DSS       (DosStartSession)   (C) P.Fitzsimmons
91/09/02 X\n");
     printf("X                                             Version
0.00 X\n");
     printf("X Usage:   DSS [options]  [program
arguments] X\n");
     printf("X Purpose:  Start a new session.                         
 X\n");
     printf("X Options:  /F    - Switch program to foreground.        
 X\n");
     printf("X           /WIN  - Run in a VIO window session.         
 X\n");
     printf("X           /FS   - Run in a full screen session.        
 X\n");
     printf("X           /PM   - Run as a PM program.                 
 X\n");
     printf("X           /WAIT - Wait for program to complete (default
 X\n");
     printf("X                   is asynchronus)                      
 X\n");
 //  printf("X

printf("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX\n");
 }
