You can write C++ programs for three of the environments that WebSphere(R) MQ for z/OS supports:
When you have written the C++ program for your WebSphere MQ application, create an executable application by compiling, pre-linking, and link-editing it.
WebSphere MQ C++ for z/OS is implemented as z/OS DLLs for the IBM(R) C++ for z/OS language. Using DLLs, you concatenate the supplied definition side-decks with the compiler output at pre-link time. This allows the linker to check your calls to the WebSphere MQ C++ member functions.
To build a WebSphere MQ for z/OS C++ application, create and run JCL. Use the following procedure:
In addition, for CICS applications you need to:
Be sure to specify the /cxx compiler option.
To run batch or RRS batch programs, include the libraries thlqual.SCSQAUTH and thlqual.SCSQLOAD in the STEPLIB or JOBLIB data set concatenation.
To run a CICS program, first get your system administrator to define it to CICS as a WebSphere MQ program and transaction. You can then run it in the usual way.
