Equivalenced Simple Variable

An equivalenced simple variable declaration associates a simple variable with a

location that is relative to the 'SG' base address.

type

is any data type except UNSIGNED; specifies the data type of identifier.

identifier

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

'SG'

a symbol that 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 boundary.

is the word or byte offset, relative to the base of previous-ident, where the

equivalenced variable is placed. For example, if a and b are declared:

INT a[0:9];

INT b = a+5

then b is placed at a[5].

offset

an equivalent INT values in the range 0 through 63.
