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 type and parm2 type. The last three letters indicate the math function performed. In these examples, the function performed is the absolute value (ABS).
