>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.

Hello Bob!

Although I read Fred Taylor excellent answer, (in the future I will use it, too)
SYS(3051) is usable too. This set the reprocess time interval. The minimum is 100 millisec. So, if SET REPROCESS TO 1, makes 1 additional try after an unsuccesfull locking, and you set reprocess time interval to 100 millisec, it is guaranted, that you get answer for locking whithin 100 millisec.
