Using Global Addresses
1. Constant definition is done as follows:
#pragma CONST_SEG __GPAGE_SEG PAGED_CONST
const unsigned char cub_far_const=1;
#pragma CONST_SEG DEFAULT
2. Constant declaration is done as follows:
#pragma CONST_SEG __GPAGE_SEG PAGED_CONST
extern const unsigned char cub_far_const= 1;
#pragma CONST_SEG DEFAULT
3. A pointer pointing to such a variable will be defined as follows:
const unsigned char *__far ptr_on_far_const;
