I am trying to read data from a MQ using below command.

Code:

EXEC    CICS                    RETRIEVE                   
                                INTO (START-DATA)           
                                LENGTH(WSC-RETRIEVE-LENGTH)


After the retrieve I see the value in WSC-RETRIEVE-LENGTH as 2380 (Which included 332 bytes of MQ header, so tactful data retrieved is 2048 bytes).

But the actual length I am expecting is more than this and the data is getting truncated.

I checked with MQ admin, they told Queue is setup to receive 100MB length.

How can I get full length of data? Do I need to code multiple RETRIEVE commands?

The RETRIEVE command retrieves data stored by expired START commands,so to read any data from MQ you will use GET.
LENGTH- Upper limit of 32763 bytes on LENGTH is allowed.

You will just need to pass the MQ name into START-DATA and then use GET to access the MQ.
Please read all the related documentation and clear up the concepts before attempting it to code.
