     This is some code I put at the begging of most of my
     programmes to reconize the current ms-dos switch char...


getswitch()
{
union REGS inregs, outregs;

inregs.h.ah = 0x37;
inregs.h.al = 0;
intdos(&inregs,&outregs);       /* find the switch char */

schar = outregs.h.dl;
}

    To set the switch, you would write a function like:

putswitch(c)
char c;
{
union REGS inregs, outregs;

inregs.h.ah = 0x37;
inregs.h.al = 1;
inregs.h.dl = c;
intdos(&inregs,&outregs);
}
