Tried to re-create the problem, but couldn't. When I manually write the file and REMOVE, it's all OK. Here's the create string:
KEYED "PFILE",[1:1:4]+[2:1:8]+[3:1:5]+[4:1:5]+[5:1:5]+[6:1:2]+[7:1:2]+[8:1:2],[1:1:4]+[2:1:8]+[15:1:4]+[3:1:5]+[4:1:5]+[5:1:5]+[6:1:2]+[7:1:2]+[8:1:2],0,-1024,BSZ=8,OPT="2",SEP=$8A$
There are 14M records in the EFF file, totaling 9GB. It's been around for YEARS, and just threw this one out. I thought it might be a file structure problem, so I ran a File Utility Check on it...no problems.
Strange occurrence. If it happens again, we'll see about the helpdesk ticket.
Thanks for the consideration.
