Ramon,

if you want to use format TCPL0100, it's very simply. Bellow are few
(most important) lines of source code.

*----- Variable declaration
D       #AppIdent       S       9B      0
D       #UsrIdent       S       10A
D       #UsrLen S       9B      0
D       #AuthStr        S       10A
D       #AuthStrLen     S       9B      0
D       #IPAddr S       15A
D       #IPAddrLen      S       9B      0
D       #RtnCode        S       9B      0
D       #UsrPrf S       10A
D       #Password       S       10A
D       #InitLib        S       10A

C       *ENTRY  PLIST
C       PARM    #AppIdent                       Input
C       PARM    #UsrIdent                       Input
C       PARM    #UsrLen                 Input
C       PARM    #AuthStr                        Input
C       PARM    #AuthStrLen                     Input
C       PARM    #IPAddr                         Input
C       PARM    #IPAddrLen                      Input
C       PARM    #RtnCode                        Output
C       PARM    #UsrPrf                         Output
C       PARM    #Password                       Output
C       PARM    #InitLib                                Output

Hier is a place for your logic. This depends on you. After that you
should set value #RtnCode. This value indicates whether the logon
operation should be accepted or rejected. If it's nessesary you should
set #UsrPrf, #Password, #InitLib.

Example :

C       EVAL    #RtnCode        =       0       (reject the logon
operation)

C       EVAL    #RtnCode        =       1       (continue the logon
operation with the specified user identifier and authentication string)

The valid values are : 0 - 6.
Sorry for my English. J hope you can understend me.

regards
