i have an A31 message that needs to go to a recieving system. it works ok but on occasion there is no PV1 info to go with the A31 and it is required by the recieving system and errors out when it isnt there. how would i add a null to the first segment in either an xlate or tcl? i have tried a few different ways in an xlate but cant seem to get it to work.
Thanks for your time
