Well, I reiterate. Pointers. The solution is pointers. :-)

If the data field of this structure is a pointer to
the variable length array, then you can store as many
of these structures in an array as you like.

William asked for an array of different structures,
which sort of turns the definition of an array
topsy-turvy. But *this* problem can be solved with
pointers, I'm sure of it. :-)

Cheers,

David
