Is there any way we can check the queue depth using Q[MA01] Program? 
I tried various options, but not able to achieve it. Thanks. |

?

Thanks for the reply jsware.
But my question is how to check the queue depth of a queue using the support pac MA01[Q Program]. |

My question is why would you want to?
MA01 is essentially an application program. MQ apps should not be aware of queue depth - they should read the queue until empty.

I am trying to read the queue and write into a file. If the queue is empty its creating an empty file which i want to avoid.
So, if its possible to check the queue depth, i can do a write to file only if the queue depth is greater than 0. |

How about checking the file length after q program has written the queue contents to a file? If the file length is zero, there were no messages in the queue. Easily checked in a Win/UNIX script.

There is a return code which might be different for an empty queue - try it (use parameter -Vc to map to 0,4,8 for script purposes).
And/or use the parameter -v2 which will report each MQGET to stderr.
