Subject: Int 10H Function 13H - How Do I access BP from C ?

I'm trying to access the Int 10 Function 13 ( Write string in teletype mode )
from Microsoft C 5.10. Everything has worked out fine so far, but today I found
out that the calling convention requires the offset of the string to be stored
in the BP register ! (BasePointer actually).

Now I wonder, is there a way to set the BP from C, or do I have to write a
.asm-hack that first saves the BP before the actual call, and then restores
it.(Which if I'm not wrong requires an update to MSC 6.0)

Any comments appreciated !
