Unresolved References
If an external reference in an object file refers to an entry point that is not among the
code blocks in that object file, the external reference is called unresolved. Unresolved
external references cause warning messages, but are allowed. They are expected to
be resolved by the fixup operation of the system loader. If the compiler cannot resolve
an external reference to a non-COBOL routine, it must at least be able to validate it.
When the compiler processes a CALL statement that calls another COBOL program,
but cannot find the other COBOL program, it delivers a warning message and
produces an object file.
