Q.
When I declare the function (void_far) type, a 4-byte area is reserved for this. Why isn't a 3-byte area (0 - FFFFFFH) reserved?
A.
The compiler will always assign a 4-byte area for a function address because of the compiler specification. This is also applied to
the address reservation of regular variables as well. When a function indirect-call is defined in a structure, and even this function is
PACKed, the function will also hold 4 bytes.
