In C18 a union can be described as follows

typedef union _IP_ADDR
{
    BYTE        v[4];
    DWORD       Val;
} IP_ADDR;


Then memory may be referenced as follows [after a variable IP of type
IP_ADDR is declared]
i=3;
IP.v[i];

Can a similar member reference be used with bits.

That is instead of referencing a bit member in the union below as

iomask.bits.b0;

Can it be referenced as

iomask.bits[i]; or perhaps iomask.bits.b[i];

Experimenting with the compiler seems to indicate that it is not possible.

Pointers to examples etc would be greatly appreciated or even what to google
for.

      union
        {
            struct
            {
                unsigned char b0:1;
                unsigned char b1:1;
                unsigned char b2:1;
                unsigned char b3:1;
                unsigned char b4:1;
                unsigned char b5:1;
                unsigned char b6:1;
                unsigned char b7:1;
            } bits;
            BYTE val;
        } iomask;
