Declaring Read-Only Arrays

A read-only array declaration allocates storage for a nonmodifiable array in a user

code segment. Read-only arrays are sometimes referred to as p-relative arrays,

because they are addressed using the program counter (the p register).

type

is any data type described in Declaring Arrays on page 8-2 except UNSIGNED.

The data type of a read-only array cannot be an address type.

identifier

is the identifier of the read-only array.

range

lower-bound

is an INT or INT(32) 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 or INT(32) 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 the number of elements initialized

minus one.

'p'

specifies a read-only array.

type identifier

'p' := initialization
