>>Hi all -

>>I don't think I've ever experienced this error in any of the apps I've been involved with. Currently working on a very old VFP app running under VFP 8.0 (Version 08.00.0000.2521) and encountering this error when a PRG attempts a COPY TO (lcRptFile) FIELDS &lcFldList. TYPE CSV command.

Yeah, that's a good idea. I'm going to wrap the call in a TRY/CATCH and re-try the COPY once or twice and see if that solves the issue. While I'm in there won't hurt to move the record pointer and see if that solves the issue. Thanks.
