Library Programs
If you are using the non-CRE or OSS environment, you cannot put an HP COBOL
routine in the user library (because you cannot compile it with the ENV LIBRARY
directive).
If you are using the CRE, you can compile an HP COBOL program with the ENV
LIBRARY directive and put it into a user library if the program satisfies these criteria:
•
It is not a main program.
•
It is an initial program (its PROGRAM-ID paragraph specifies INITIAL).
•
It is a separately compiled program (it is not embedded in another program).
•
It does not contain any other programs.
•
It does not specify the GLOBAL phrase on any level-01 record descriptions.
•
It does not reference any external data items or external files.
•
It does not have an Extended-Storage Section.
•
It does not have a PROGRAM COLLATING SEQUENCE clause.
•
It does not contain SQL/MP statements.
