You can customize logon panels and logon help panels in a variety of ways, including adding and removing fields.

You can use the source of logon panel modules and logon help panel modules to suit the needs of your installation. You can also create your own panels.

The source for the logon panel module (IKJLPENU), the logon panel module with password phrase support (IKJLQENU), and the logon help panel module (IKJLHENU) is included in SYS1.SAMPLIB. Logon panel load modules are installed in SYS1.LPALIB. Logon help panel load modules are installed in SYS1.LINKLIB.

To install a logon panel load module that you have customized, you must code and assemble the logon panel csect and link it into the LPA library.

A logon panel load module consists of a single csect divided into two parts. The first part is header information that contains offsets of the fields defined in the second section. The second part of the csect is the 3270 data stream instructions that comprise the logon panel.

The logon help panel load module consists of the same two parts, but the header does not contain address attributes.

If your installation has a language feature installed, logon and logon help panels are available in that language. You can customize logon panels and logon help panels for a particular language by using logon panel and logon help panel csects. The source for the logon panel csect is in SYS1.SAMPLIB. Customizing TSO/E for different languages describes how you can select a language for your installation or for users in your installation.
