RACF/UADS: If this bit is set on, the source for the default information is from the RACF® data base. If this bit is off, the source for the default information is the UADS data set.
DBCS: If this bit is on, the language code selected, either by or for the user, is a double-byte character set (DBCS) language. The 3270 data stream information can contain DBCS characters.
IBM-defined field refresh: You can set this bit on to request that the LOGON command refresh the IBM-defined fields in the 3270 outbound data stream with the values specified in the parameter entries.
User-defined field refresh: You can set this bit on to request that the LOGON command refresh the installation-defined fields in the 3270 outbound data stream with the values specified in the parameter entries.
Don't issue RACROUTE REQUEST=VERIFY: If IKJEFLN2 performs RACF processing and you do not want the logon processor to issue a RACROUTE REQUEST=VERIFY, IKJEFLN2 must set the "Don't issue RACROUTE REQUEST=VERIFY" bit on.
Re-prompt: If you wish to re-prompt a TSO/E user for a field, you must set this bit on. The Re-prompt Code parameter (parameter 15) describes the field for which the re-prompt is necessary.
Help Text: If you wish to display help text, you must set this bit on. The logon processor then displays the help text as requested in the Help Panel Number parameter (parameter 13).
