JB>What is the DOSCALLS.LIB library?  

That's the library with all the DOSCALLS in it .  
It links calls in an OS/2 program to the dll's that contain the routines for
OS/2 system calls.  It's a misleading name, they are OS/2 protected mode calls,
DOS, VIO, MOU, and KBD routines.  The DOS category doesn't have anything to do
with PC-DOS, though, and so...

JB>Can it be used with VisualBASIC 

No.
