Call interface to math services
The syntax for math services has two forms, depending on how many input parameters the routine requires. The first four letters of the math services are always CEES. The fifth character is x, which you replace according to the parameter types listed in Parameter types: parm1 and parm2. The last three letters name the math function performed. In the following examples, the first function performed is the absolute value (ABS), and the second function is the positive difference (DIM).
