+
-
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.

location relative to the base address of the system global (.SG) or the extended system
global (SGX) data area.
STRING
