How to display local queues where curdepth reached its maxdepth in ibm mq - ibm-mq

Question

I want to display all local queues where curdepth reached its maxdepth.
I understand that the below where condition in runmqsc will not work.
DIS QL(*) WHERE(CURDEPTH EQ MAXDEPTH)
I am trying to parse it with sed and awk but not even close as I am no expert in scripting
Please help in getting desired output. Thanks

Isn't this like trying to squeeze a fully blown up balloon into a wine bottle?
It would seem far, far simpler to just run a Java/MQ/PCF application to get both the current and maximum depths and compare the values.
Here is a simple (complete) Java/MQ/PCF application to do that:
Note: It has a filter on the PCF command to only return queues with a current depth greater than zero. Hence, the queue manager's command server will return less data and make over all processing faster.

* Program Name
* MQCurrentDepthMonitor01
*
* Description
* This java class issues a PCF "inquire queue" request message for all ("*") local queues
* with a queue depth greater than 0 (zero) of a remote queue manager and
* (1) output an error message if current depth is the same as max depth or
* (2) output a warning message if current depth is within 90% of max depth.
*
* Sample Command Line Parameters
* -m MQA1 -h 127.0.0.1 -p 1414 -c TEST.CHL -u UserID -x Password
