Thanks Mike - that makes it more likely, "something silly" at this end.
Yes, I meant the HISTORY file (we actually ship the, "daily" HISTORY file that ESAMAP builds from the HISTORY file created by ESAWRITE - the one with the date as the filetype). We use NETDATA to pack the file and ship it via RSCS rather than go via tape but otherwise we're doing similar things. Our ESAWRITE / ESAMAP (as shown in the header of the HISTORY records) is at 3.5.2.5 and our MXG is at 23.05. I'd be interested in knowing your ESAWRITE / ESAMAP level. Suggest we now take this off-list as it looks like a, "minority interest topic" and I'll post a conclusion once one's achieved. Regards Jeff
