Installing the page format table

The default page format table is packaged in the module EZAPPPFT. The EZAPPPFT module is shipped in the form as a ready-to-use load module or as sample source code. The sample source code form can be modified by the user.

Procedure

To install a user-modified version of EZAPPPFT, proceed as follows:

Code the modified version of the module, using the IBM-supplied EZAPPDPF macro. See EZAPPDPF for details about how to use the macro to create the table.
Assemble and link-edit the module into a partitioned data set different from that used for the IBM-supplied version of the module. This prevents the module from being deleted during any subsequent re-install of NPF.
On the JCL to start the VTAM® capture point application, provide a STEPLIB DD statement specifying that partitioned data set. For example:
```
//STEPLIB DD DSN=xtable.loadlib, DISP=SHR
```
In this example, xtable.loadlib is the name of the partitioned data set that includes the tables as members. See Operating the NPF VTAM capture point for a sample startup procedure.

Results

To dynamically replace the current version of EZAPPPFT with a new one while the NPF VTAM capture point application is running, respond to message EZY0837I with the following code:

nn, RELOAD EZAPPPFT

After the dynamic replacement is complete, the new version of the table will be used for new sessions, but already-started sessions will continue to run under the rules from the old table.
