amqsbcg0.c only allocates a buffer size of 32767
#define BUFFERLENGTH 32767 /* Max length of message accepted */
rc 2080 says it tried to get a message larger than this.
You must make modifications to amqsbcg0.c and rebuild it before you can browse larger messages. Either increase the buffer size and BUFFERLENGTH or let it get truncated messages and only show the 1st x bytes of the message.

You can modify amqsbcg0.c, recompile it, and you should be good to go.
However, if you run into messages that are larger than the value you pick, you'll still get the problem. You might consider altering the program to accept a truncated message (MQGMO_ACCEPT_TRUNCATED_MSG) and then you can print a warning that the message data is truncated. |

Hi,
If you are looking for a stand-alone application to browse / edit messages in a queue, then might I suggest you try out MQ Visual Edit. It can do that plus more.
To download a 30-day trial of MQ Visual Edit go to:

If you really need to browse the complete message content, I would allocate the buffer dynamically. When the MQGET returns the 2080, it also gives you the size of the message on the queue. Just allocate a buffer this size and re-issue the MQGET.
Would you be interested in a java version of amqsbcg? I can't believe bower5932 didn't mention this one, since he is the author 
Go to http://www.developer.ibm.com/tech/sampmq.html and look for mqbrowse.java.
