* Product Number : 5695-137 *
* *
* Module Name : CSQ4CVB3 *
* *
* Environment : CICS/ESA Version 3.3; COBOL II *
* *
* CICS Transaction Name : MVB3 *
* *
* Description : Sample program to show a reply being developed *
* and sent in response to an input message. *
* The account file is read; if the account is *
* known, data from the file is used in the reply,*
* if the account is not known, an appropriate *
* response is sent. *
* *
* The queue on which the input message is to be *
* found is identified in the trigger information *
* available to the program. *
* *
* Function : This program provides the checking account *
* query function for the credit check sample *
* See IBM MQSeries for MVS/ESA Application *
* Programming Reference for details. *
* *
* Dependency : Uses VSAM file known to CICS as 'CSQ4FIL' *
