How would you obtain a far address from segment and offset address of a memory location?

Answer

Pointers to far objects are stored using four bytes (32 bits). The bytes are stored little endian or low to high order. The first word contains the 14-bit memory offset (bits 14 and 15 are always 0). The second word contains the page number (or segment number for function pointers). The memory address is calculated as follows:

Variable Address = (Page * 0x4000L) + Offset

Function Address = (Segment * 0x10000L) + Offset
