DOSCALLS.LIB and OS2.LIB are import libraries for the DLL's of the OS/2
system. They resolve all references to system calls and place dynamic
link records into the executable which are detected by the loader and
replaces by addresses of the actual loaded DLL entries. The difference
between these two libraries is, that DOSCALLS.LIB does originally only
include definitions for the base system of OS/2 without the Presentation
Manager where OS2.LIB contains definitions for all system calls.
When linking base applications (VIO programs), it makes no difference
(except speed at link time ?) which library you use.
