I think the flags are "don't care", meaning return in indeterminate state.
You can always test it.  

Any how, I got a bone to pick with Microsoft C mixed-language
facility.  My department put down three hundred big ones for the 
compiler and interface seems not to work in a consistant way.  
When I finally got the C-main-program/Machine-assembler-subroutine to
work (both Microsoft) with a small size routine, I started to put a 
bigger assembler subroutine in (about 30k output code), but the
program failed, even after much debugging.  I have written 
nearly 1 meg of 8086 assembler (measured by output codes) with C 
as main program (Microsoft assembler, cheap $20 MIX C compiler), and
can always get them to work the way I want.  Can anyone comment
on working with C/Assembler interfacing with Microsoft C compiler and
Microsoft Assembler, and maybe speculate what I am doing wrong.  Also,
due to departmental decision, I have to use Turbo C and Turbo Assembler,
anyone's got any experience and thing to say?

Thanks in advance.
