Array Redefinition

An array redefinition associates a new array with a previous item at the same BEGIN-

END level of a structure.

type

is any data type except UNSIGNED.

identifier

is the identifier of the new array.

lower-bound

is an INT constant expression (in the range -32,768 through 32,767) that specifies

the index (relative to the zeroth element) of the first array element you want

allocated. The default value is 0.

upper-bound

is an INT constant expression (in the range -32,768 through 32,767) that specifies

the index (relative to the zeroth element) of the last array element you want

allocated. The default value is 0.

previous-identifier

is the identifier of a simple variable, array, substructure, or pointer previously

declared in the same structure. You cannot specify an index with this identifier.

Usage Considerations

In a redefinition, the new item and the previous (nonpointer) item both must have a

byte address or both must have a word address. If the previous item is a pointer, the

data it points to must be word addressed or byte addressed to match the new item.
