Design Guidelines

• Be careful not to end a conversation inadvertently.

  A conversation is a task-level resource in CA IDMS/DC. When the task ends, any ongoing conversation will be deallocated automatically. So do not use:

  • DISPLAY
  • LEAVE ADS NEXT TASK CODE
  • LINK (to a program that will pseudoconverse)

  Using any of these commands will deallocate your conversation.

• Be aware of the location of the allocated dialog.

  The CA ADS allocated task runs as a nonterminal task. Because you can not point to a secondary load area or load library on the ALLOCATE command, the allocated dialog should reside in the CA IDMS/DC default load search sequence.

  If you want to use a secondary load area or load library, you must override the search sequence by:

  • Using the SECURITY parameter on the ALLOCATE command issued by the primary dialog.
  • Dialogs which exist in secondary load areas can be accessed in the client task thread by using a signon profile associated with that user containing DCUF SET DICTNAME or LOADLIST to change the search sequence for the secondary dialog.

    For server task threads a new system loadlist must be created and the secondary dictionary entry must be coded prior to the primary dictionary entry. A typical loadlist follows:

    ADD LOADLIST NEWLOAD
        DICTNAME IS APPCDICT VERSION IS 1
        DICTNAME IS USER-DEFAULT VERSION IS USER-DEFAULT
        DICTNAME IS SYSTEM-DEFAULT VERSION IS SYSTEM-DEFAULT
        LOADLIB IS USER-DEFAULT
        DICTNAME IS USER-DEFAULT VERSION IS 1
        DICTNAME IS SYSTEM-DEFAULT VERSION IS 1
        LOADLIB IS SYSTEM-DEFAULT
    MOD SYSTEM nnn
        LOADLIST = NEWLOAD
