CON

CON={aa}
    {(aa[,L][,NOJES3][,modespec])}
    {modespec}
    {NONE}
    {(NONE[,L][,NOJES3][,modespec])}
    {NOJES3} 
    {(NOJES3[,modespec])}
   

The two alphanumeric characters (aa) are appended to CONSOL to form the name of the installation-created CONSOLxx member of SYS1.PARMLIB.

If you specify the L option, the system lists all of the statements read from the CONSOLxx member on the operator's console.

If you specify NONE, the system will use all the IBM® defaults for the CONSOLxx parmlib member to bring up the system. For information about when you would want to specify CON=NONE, see z/OS MVS Planning: Operations.

When operating JES2 on a system with JES3 installed, IBM suggests the use of the NOJES3 option to allow the comma to be omitted between the REPLY id and the command text when using short form reply.

The NOJES3 option has no effect when specified on a system that does not have JES3 installed.

The aa or NONE specification, if used, must precede the NOJES3 option. The L option, if used, can precede or follow the NOJES3 option. If you specify only NOJES3 on CON=, the system assumes you wanted (NONE,NOJES3).

The NOJES3 option, if specified, remains in effect for the duration of the IPL. If you specify NOJES3 with an error, (such as CON=(aa,NOJES3) for a CONSOLxx member that does not exist, or CON=(NONE,NOJES3) when a CONSOLxx member is required), the NOJES3 value remains in effect, regardless of how you respond to the system's prompt for CON=. To remove the NOJES3 specification, you must reload the initial program and omit the NOJES3 option when you respecify the CON= parameter.

The console support mode option modespec is either DISTRIBUTED or SHARED. The default is DISTRIBUTED. See z/OS MVS Planning: Operations for more information.

Value Range: NONE or any two characters (A-Z, 0-9, @, #, or $) and, optionally, NOJES3, DISTRIBUTED, or SHARED.

Default Value: CON=(NONE,DISTRIBUTED)

Associated Parmlib Member: CONSOLxx
