>How to do it? What I want to do is select a record, try to get a rlock on it, if successful insert that value into another table, then modify the record's "available" field so it won't be used again... I just need to figure out (with your help <grin>) how to send a rlock to vfpodbc.

I haven't tried this, but I'd guess you'd need to write a stored procedure and trigger it as a row or field validation rule. I'm not sure what locking and buffering options are avaialble under the VFPODBC driver; you'll need to consult the docs that accompany the VFPODBC driver (VFPODBC.TXT and DRVVFP.HLP; the latter contains the list of supported and unsupported VFP commands under the ODBC driver.) FLOCK(), RLOCK(), the TRANSACTION syntax, TABLEUPDATE() and TABLEREVERT() are supposedly supported.
