   My reference was to OS/2 calls *from*a* DOS app, which is why I 
   say it's incomplete.

   I'm still searching for a coherent explaination/layout of the 
   Family Mode(?) API.

   They could  be used within a single VDM's address space, but that 
   would only duplicate what the application could do for itself, 
   so...
