DB2 Server for VSE & VM: Application Programming

Compiling the Program

After you successfully preprocess your program, you can compile it using your normal host language compiler. By preprocessing, you have already done all the translating that the program needs for the database manager. Just use the new code that you got after you preprocessed. Compile this code as you would any other progrm, using the usual compilers.

This book does not cover the specifics of compiling your host-language code. However, there are several special rules for SQL programs, depending on the host language, that you must follow:

• If your PL/I application program contains DBCS data, you must specify the GRAPHIC option for the compiler. If your COBOL application program contains DBCS data or is reentrant, the output of the DB2 Server for VM preprocessor must be processed by the COBOL II Release 2 (or later) program.
• If the QUOTE option is used for the DB2 Server for VM COBOL preprocessor, it should also be used for the COBOL compiler.
• If the NOSEQuence option is used for the DB2 Server for VM C preprocessor, the NOSEQ and MARGINS (1,80) options must be used with the C compiler.
• If the compiler provides a mechanism whereby run-time program interrupts are trapped before control returns to CMS, the database manager may not identify that an abnormal termination has occurred. As a result, an implicit COMMIT is executed instead of an implicit ROLLBACK. See the host language appendixes for a discussion of program interrupts.
