Most compilers have some minimum requirements for comp storage. For example, the smallest unit of storage may be 2 bytes, so even if you specify PIC 9 (only 1 digit), the compiler will reserve two bytes.

Only fields used in arithmetic computations should be numeric.

RETURN-CODE is a 2 byte binary field. Hence, it can very much be defined as a numeric field also. It is defined as alpha numeric field, i.e., PIC X(02) because it occupies 2 bytes and COBOL converts numbers in binary to char format when they are accessed through a variable of definition PIC X(n). RETURN-CODE can very much be defined as PIC S9(04) COMP or PIC 9(2) also.Please correct me if I am wrong.

When we code we make sure that variables are defined in such a manner to handle every condition. Though return codes are numeric,we generally use alphanumeric variables to store it as alphanumeric variables can store not only numbers but also alphanumeric characters which improves functionality.
