Equivalent of C language union in PCML?

Hi,

I'm calling an API that returns data in two different formats depending on
one of the input parameters.  Therefore I need to interpret the data as
either struct A or struct B, and the two structs are in the same memory
position.  This is roughly equivalent to a C language union.  Does anyone
know if you can achieve the same effect by specifying the same offset for
both structs explicitly?


Thanks for any help.


Regards,


Niall
