Abbydale Systems LLC - QECHO Program

As ever, you use this free code at your own risk.

Feel free to use the free software on this site but please honor the copyright.

QECHO is a Cobol program that simply reads a message from a queue and writes the exact same message back onto the reply queue.

QECHO follows most good WebSphereMQ programming techniques, except for one very important difference. The difference is that it will run forever or until it gets a shutdown message (<SHUT>). It can, however, be canceled without any issues if needed. The program will also shutdown if the Queue Manager is closed down.

There are two parameters required for QECHO. These are Queue Manager name and input queue name.

The following parameter rules apply:

The name of the Queue Manager must be the first parameter passed to the program.
Parameters must be separated by a comma.

	QECHO & QUEPUT Loadlib XMI File	This is the link to the load library dataset in TSO TRANSMIT (XMIT) format that contains the 2 programs, QECHO & QUEPUT. This file is a TSO TRANSMIT file and should be transferred to the z/OS system using a file transfer program. The file must be transferred as a BINARY file. It must be transferred as a fixed blocked, 80 byte file. Once the file is on z/OS it will have to be received. To do this you use the TSO RECEIVE command. Please refer to the IBM RECEIVE command for details on the use of this TSO command.
