Hi Nancy,
You can add your unique file name to in the MetaData part of the message, using a statemnet as follows. This example uses a FILESET protocol.
# Set a unique file name here
msgmetaset $mh DRIVERCTL “{FILESET { {OBAPPEND 1 } { OBFILE ${UNIQUE FILE NAME}.$fileExt } } }”
echo ” FileName: message reset with filename. “
Let me know if you need more detail.
Thanks
