Equivalenced Simple Pointer

The equivalenced simple pointer declaration associates a simple pointer with a location

relative to the base address of the system global ('SG') or the extended system global

('SGX') data area.

type

is any data type except UNSIGNED and specifies the data type of the value to

which the pointer points.

.EXT

.SG

.SGX

are indirection symbols (see Table 2-7 on page 2-7).

identifier

is the identifier of a simple pointer to be made equivalent to 'SG'.

'SG'

denotes a 16-bit system global address.

index

is an INT constant that specifies the offset of the element in previous-ident to

which the equivalenced pointer or variable refers. Specify index only with direct

variables. index must end on a word (16-bit) boundary.
