Writing a logon pre-display exit (IKJEFLN1)
You can use the logon pre-display exit, IKJEFLN1, to further customize
the logon process. This exit is invoked if:
- Logon language load modules are present in the LPA
- Exit IKJEFLD/IKJEFLD1 does not set the
Don't Prompt
control bit
The logon processor can invoke this exit several times during logon processing. If a re-prompt occurs for any data that is entered by the user, the logon processor invokes this exit.
You can write a pre-display exit to perform the following:
- Supply any data for IBM® or installation-defined input fields
- Indicate that the logon processor should refresh fields in the 3270 outbound stream with data specified in the parameter entries defined for each field
