When you are browsing files, the STARTBR and READNEXT positions are lost when a SYNCPOINT command is issued. This point is extremely important when you are using MQ series queues,where you may be required to issue a SYNCPOINT after you get or put the message.
What is the early warning signal for this ? - Getting INVREQ in a READNEXT or ENDBR (where STARTBR and previous READNEXT commands were all succesful)
