The following set of clauses is optional. You can specify all or none of them, and in any order, but each clause defaults to a particular value if it is not specified.
- Specific function name (see SPECIFIC Function Name Clause)
- Function class (see Function Class Clause)
- Parameter style (see Parameter Style Clause)
- Deterministic characteristics (see Deterministic Characteristics Clause)
- Null call (see Null Call Clause)
- External data access (see External Data Access Clause)
If you specify any of these clauses, you must specify them sequentially prior to specifying the External Clause (see EXTERNAL NAME Clause), which can be followed by a Parameter Style Clause see Parameter Style Clause).
