* CICS Transaction Name : MVC1 *
* *
* Description : Sample program to set and inquire about *
* two queue attributes *
* *
* Function : This program allows the user to set and *
* inquire about the INHIBIT-PUT and INHIBIT-GET *
* attributes of a local queue *
* *
* Restriction : The queue name must start with 'CSQ4SAMP'. *
* This is to avoid any accidental interference *
* with the queues at the user's installation *
