DEC/VAX to IBM CICS Interface

I am trying to establish communications between a DEC/VAX and an IBM CICS environment using LU 6.2. I am able to receive the data sent by DEC/VAX in my CICS program (Invoked by LU 6.2) and access the remotely located database and retrieve the information. However, when I try to send it back to DEC/VAX through my CICS task, the CICS task locks up. I have been able to determine that I am in a receive mode in the CICS task and need to change it to send mode before trying to send the information.But I have been trying for the last two weeks without any success. Does anyone have an idea what could be wrong? Any help will be greatly appreciated…
