Downloading the object library in z/OS

This section is under construction. It will be cribbed from the instructions on the download page. A key thing mentioned is our use of ROKOB204 in the documentation to refer to the downloaded object library.

Linking the Model 204 ONLINE load module

After downloading the object library, one of the members of ROKOB204 is named JZLONLN - the basic ONLINE link JCL. You can use this to link-edit the Model 204 online. It contains a number of choices which you can make to modify this basic JCL; each choice is indicated in the JCL by a line which ends with <<.

Most of the choices are "optional", in the sense that a working ONLINE does not require the indicated modification, although, for many customers' environments, a modification will be needed, for example, to select an external authorizer.

1	Only one modification is always required, based on whether the ONLINE is to use RSQL (for Connect*) or not: To link an ONLINE which does use RSQL, you must un-comment the INCLUDE ROKOB204(LKSQLONL) statement. To link an ONLINE which does not use RSQL, you must un-comment the INCLUDE ROKOB204(LKNOSONL) statement.
2	The other modification frequently needed is to use an external authorizer such as RACF or ACF2. If you do, you must: Prepare the appropriate xxxPARM object file (e.g., RACFPARM orACF2PARM), adding that to a *different* object library (with the same DCB attributes as ROKOB204). We refer to this as your local object libary (it will also be used for other assemble output, such as your FUNU). In the SYSLIN DD *, un-comment the appropriate INCLUDE statement(s) for your external authorizer. Note: If you use ACF2, there are two INCLUDE statements to be un-commented; one refers to your system ACF2 library. You must un-comment the ACF2 DD as well, and fill in the DSN for that library.
3	If you have other programs which you assemble for your Model 204 ONLINE module, for example, FUNU, they should be assembled into your local object library (creating one - with the same DCB attributes as ROKOB204 - if you have not already created one for the external authorizer xxxxPARM object file). You do *not* need to add additional INCLUDE statements for FUNU or other locally assembled object files - they are already present in the include streams from ROKOB204.
4	Hence, there are two choices for the ROKOB204 DD statement: If you have a local object library, fill that in for the first concatenation, and fill in the ROKOB204 DSN for the second concatenation. If you do not have a local object library, there is only one dataset for the ROKOB204 DD - your ROKOB204 library.
5	Finally, change the DSN of the SYSLMOD DD to the load module library you have allocated for it.

The modified JCL is now ready to run.

Notes:

• There is not a separate link step for BATCH204. It is not maintained as a separate module; the same module as ONLINE is used, with a BATCH204 alias.
• The object library has the authorization zap pre-applied, so you *do not* need to get a new one from the web site.
• It also has the maintenance zaps (as of the time the stream was prepared) pre-applied, so you *do not* need to apply any maintenance.
