I don't see a way to avoid SET REPROCESS. Issuing a "SET REPROCESS TO" without a nAttempts gives me a syntax error. Leaving it untouched, gives the FoxPro default of 0 (which is try forever, just like AUTOMATIC) if I issue a LOCK(), or RLOCK(), or FLOCK().

>>According to the help file, SET REPROCESS to AUTOMATIC, is the same as SET REPROCESS to –2, is the same as SET REPROCESS to 0 … Try forever and let the user terminate with the escape key. SET REPROCESS TO –1 is also the same, except hitting escape won’t terminate it.

>>According to help, nAttempts (as in SET REPROCESS TO nAttempts) specifies the number of times Visual FoxPro attempts to lock a record or file AFTER AN INITIAL UNSUCCESSFUL ATTEMPT, so SET REPROCESS TO 1 should try once initially, and then 1 additional time after the unsuccessful attempt, for a total of 2 tries.
