void pause(void)
{
    switch (mtask)
    {
        case T_DOS:
            asm {
                int 28h
            }
            break;

        case T_DV:
            asm {
                mov ax, 101ah
                int     15h
                mov     ax,1000h
                int     15h
                mov     ax,1025h
                int     15h
            }
            break;

        default:
            break;
    }
}


The code is there (partially), but ironically pause() is not called from
anywhere in the program!


rc> DV timeslicing is easy, as is Doze and OS/2

Is INT 28h safe to call in native DOS, Windows or OS/2 ?
