Define a variable pibva to be the address of the PIB (process information block) for PIN 1.
Get the address of its vs_od_ptr, then display its vs_od_ptr in hex.

func vtor
Virtual to real. Converts a virtual address to a real address.
Syntax
vtor ( virtaddr )
In Debug, if the virtual address is not resident, it is brought into memory.
In DAT, if the virtual address is not resident, an error is generated.
Formal Declaration
vtor:u32 ( virtaddr :ptr)
