Description:
Example:
_ _near8 <type specifier> <variable name>
<type specifier> _ _near16 <variable name>
_ _near16 <type specifier> <variable name>
Specifies an array or structure whose address can be calculated by an 8-bit or
16-bit address. When _ _near 8 is specified, calculates an array or structure
address using the lower 1 byte. When _ _near16 is specified, calculates an
array or structure address using the lower 2 bytes.
When _ _near8 is not specified
