Yes. Use any program that can do destructive gets - one for each message.
There's a 'q' utility program available as a free support pack. Or you could use amqsget/amqsgetc.

| I don't see amqsclear as one of the samples supplied with the product or any reference to it in the manuals. Maybe it is your own custom application. |

you can modify the existing amqsget0.c program to get messages off the queue you need to change the line containing char buffer[100]; to
char buffer[MAX_MESSAGE_SIZE];
MAX_MESSAGE_SIZE needs to the max size of your messages

| You could also change the buffer size to 1 and change the get options to accept a truncated message. |

You could try to GET and PUT Inhibit the queue, wait till IPROCS and OPROCS counts (hopefully) go to zero, and then clear it. Depending on how the app was written though this may not shake the app loose.
Clearing the queue by destructivly getting with another app is the easiest I find. And for the cases where an app opened the queue as InputExclusive, preventing this method, then Inhibiting the queue knocking out the app is the next posability, at which point you can clear the queue.
