The following note applies to many of the <expression> commands discussed in this sec-
tion:
NOTE: To use BASE, TOP, COPY BASE, COPY TOP, LOWADDR, HIGHADDR, LENGTH, and
FREEMEM <expression> commands, you must have completed the calculations on the
expression. This is done using the SEQUENCE and ORDER commands. Do not use an
expression of the segment or space itself to locate the object in question.
Examples
/* Correct example using segments */
SEQUENCE seg2, seg1 /* Calculate seg2 before seg1 */
LOCATE seg1 AT TOP OF seg2 + 1
/* Do not do this: cannot use expression of seg1 to locate seg1 */
LOCATE seg1 AT (TOP OF seg2 - LENGTH OF seg1)
+ (Add)
The + (Add) operator is used to perform addition of two expressions.
Syntax
<expression> + <expression>
