Returns the product of all the elements of an array.
Syntax
PROD(x)
Parameters
x is an array expression.
Description
The PROD function returns the product of all the elements of the array.
If the elements of x are strings, they are converted to fixed-point values. If they are neither fixed-point values nor strings, they are converted
to floating-point values. In the latter case, the result is a floating-point value; otherwise, it is a fixed-point value.
Examples
DECLARE (A(4), I) FIXED BIN (15);
DO I = 1 to 4;
A(I) = I;
END
I = PROD(A); /* returns 24 */
