Programming languages and wrappers

This section includes the implementation information that is specific to programming languages. For some languages you use wrappers so that you can make calls to Bank Wizard in a more natural way for the programming language.

Bank Wizard also includes some example programs to demonstrate how you implement and use the Bank Wizard API. Use these examples as the basis for your implementation. BWIBEXAM is a compiled copy of the C example program.

To run BWIBEXAM, set up the BWTABLES environment variable and, for UNIX, the search path for the libraries.
For the available command line syntax, run the program with no parameters.

z/OS example programs

The z/OS example programs include:

the standard C example without the .h and .c file extensions. Run with no command line parameters to display help for this program
CICS specific C example. This is the source for BWICEXAM which shows how to use BWICAPIA to interface from CICS to Bank Wizard. Run with no command line parameters to display help for this program
bwilexam - batch COBOL example
bwioexam - CICS COBOL example that shows how to use BWICAPIA. BWICAPIA provides the full functionality of the BWI API using a single CICS program.
Batjcl - example JCL for running batch programs, both the examples and the FSM
Cicsjcl - example JCL for installing Database Table Files, CICS programs and transactions
Parmlib - example parameter library used to link C/COBOL batch programs with the compiled object files.

The COBOL batch example uses a set of wrappers supplied in the bwilwrs3 source file. These wrappers are platform specific and mean the same example code can be supplied for various platforms. For example, the z/OS wrappers convert the PIC 9(9)/PIC 9 (10) types used by the main bwilexam file into the z/OS specific PIC 9(9) BINARY type. You do not need to use the wrappers if your code does not need to be portable. You can use PIC 9(9) BINARY and directly call the API function.
