1) The OP has stated that the program is written and may no longer be modified. 2) Since the program does not know when it may terminate, it is possible that the last OPEN would be just before the program is to terminate, thereby making the trace file have 0 records. Another possibility, which I am not suggesting, but only mentioning, is to use GPSAM from the CBT. This function uses subsystems to redirect Q/BSAM output to another program, similar to a "pipe". -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
