The ADD
statement is used to add two or more
operands.
This statements has two different syntax structures.
Notes:
ADD
statement
is executed, each operand used in the arithmetic operation must contain a valid
value.

operand2

Operands:
operand2 := operand2 + operand1 + ... 
ROUNDED 
ROUNDED Option:
If the keyword For information on rounding, see Rules for Arithmetic Assignment, Field Truncation and Field Rounding in the Programming Guide. 
Example:
The statement
ADD #A(*) TO #B(*)
is equivalent toCOMPUTE #B(*) := #A(*) + #B(*)
ADD #S TO #R
is equivalent toCOMPUTE #R := #S + #R
ADD #S #T TO #R
is equivalent toCOMPUTE #R := #S + #T + #R
ADD #A(*) TO #R
is equivalent toCOMPUTE #R := #A(*) + #R

ROUNDED 
ROUNDED Option:
If the keyword For information on rounding, see Rules for Arithmetic Assignment, Field Truncation and Field Rounding in the Programming Guide. 
Note:
If Syntax 2 is used, the following applies: Only the
(operand1
) field(s) left of the keyword
GIVING
are the terms of the addition, the field right of the
keyword GIVING
(operand2
)
is just used to receive the result value. If just a single
(operand1
) field is supplied, the
ADD
operation turns into an assignment.
Example:
The statement
ADD #S GIVING #R is equivalent to COMPUTE #R := #S ADD #S #T GIVING #R is equivalent to COMPUTE #R := #S + #T ADD #A(*) 0 GIVING #R is equivalent to COMPUTE #R := #A(*) + 0 which is a legal operation, due to the rules defined in Arithmetic Operations with Arrays ADD #A(*) GIVING #R is equivalent to COMPUTE #R := #A(*) which is an illegal operation, due to the rules defined in Assignment Operations with Arrays
