Issue/Introduction

Introduction

With z/OS 2.2, there is a new option for TSO available, PASSWORDPREPROMPT={ON|OFF} with OFF being the Default.
When activating that option by specifying PASSWORDPREPROMPT=ON in the LOGON-Statement of the SYS1.PARMLIB member IKJTSOnn you need to enter Userid and Password in a different way than previously. This has an effect on possible Script-procedure used to automate Logon to TSO. If the provided combination of Userid and Password is incorrect, you are logged out of the session.

So you will not see the old Logon screen after entering the userid alone:

  ---------------------------- TSO/E LOGON --------------------------
  Enter LOGON parameters below: RACF LOGON parameters:
  Userid ===> xxxxxxx
  Password ===>                   New Password ===>
  Procedure ===> pppppppp         Group Ident ===>
  Acct Nmbr ===> nnnnnnnn
  Size ===> 2048
  Perform ===>
  Command ===>

  Enter an 'S' before each option desired below:
  -Nomail -Nonotice -Reconnect -OIDcard
  -------------------------------------------------------------------

Instead of this panel you see this line:

 IKJ56700A ENTER USERID –

After entering your userid you see this:

  IKJ56700A ENTER USERID -

 xxxxxx                  

 IKJ56476I ENTER PASSWORD

After entering the correct password, you are logged on to TSO.

 

Instructions

For TPX this new Option has the consequence that you need to check your ACL script used for logon to TSO. It likely needs to be changed due to the changed data flow between terminal and TSO. A good approach is to logon to TSO without the ACL being active (Use line command 'g' instead of 's' in the Main Menu) and trace all input from the terminal and all panels received from TSO; finally rewrite the ACL.
