This parameter entry allows you to request the display of a particular help panel. If the exit requests that a help panel be displayed, the exit should set the key field of the parameter entry to X'01' and the data field should specify the appropriate panel number (in binary). The numbers of the IBM-defined help panels for the LOGON command are listed in Table 1. This exit must also set the help text control switch indicating that the LOGON command should display the help text (see Table 1).
