SUM Function
The SUM function returns a value that is the sum of the parameters. The
function type is either integer or numeric depending on the type of the
parameters, as follows:
Parameter Type Function Type
All parameters integer Integer
Numeric (some parameters may be Numeric
integer)
Syntax
FUNCTION SUM ({parameter-1}...)
Parameters
parameter-1 Must be class numeric.
Return Value
The returned value is the sum of the parameters.
If the parameter-1 series are all integers, the value returned is an
integer.
If the parameter-1 series are not all integers, a numeric value is
returned.
Example
01 TAB.
05 ELEMENT PIC S999V99
OCCURS 4 TIMES VALUE ZERO.
01 TOTAL PIC S999V99 VALUE ZERO.
:
MOVE 1.25 TO ELEMENT (1).
MOVE 3.50 TO ELEMENT (2).
MOVE 8.75 TO ELEMENT (3).
MOVE 0.25 TO ELEMENT (4).
COMPUTE TOTAL = FUNCTION SUM (1, 7, 9, 23, 85).
DISPLAY TOTAL.
COMPUTE TOTAL = FUNCTION SUM ( ELEMENT (ALL) ).
DISPLAY TOTAL.
The above example displays the following:
+125.00
+013.75
