IKJEFLD1 can return the first TSO/E command to be executed. The command can be up to 80 bytes long. IKJEFLD1 must also set the First Command bit on. The first command can be returned regardless of the settings of the Don't Prompt and No UADS bits. However, if IKJEFLD1 does not set the Don't Prompt bit and allows logon to display the full-screen logon panel, the first command is displayed on the panel and the user can modify or delete it.
