The language used to write the source code for the method defined by this signature.
The valid languages for writing methods are C and C++.
- If a method is written in C, then its language clause code is C.
- If a method is written in C++, then its language clause code is CPP.
This must be specified as LANGUAGE C or LANGUAGE CPP even if the external method routine is supplied in object form.
If the external method object is not written in C or C++, it must be compatible with C or C++ object code.
This clause is mandatory for each method signature you specify as part of a distinct UDT definition.
