Hello, I have updated my enhanced scalable Anderson Lock , i have corrected a bugin the enter() method here is the what i have corrected: == procedure TALOCK.Enter; var count1,slot:long; begin repeat count1:=LockedIncInt(count); if count1<= FSize then break; LockedDecInt(count); while count>=fsize // <-- i have changed here count1 by count do sleep(0); sleep(0); until false; slot:=LockedIncInt(fcount2^.fcount2); while Fcount1^[(slot-1) mod fsize].fcount1<>1 do sleep(0); end; === Other than that if you have noticed the following while count>=fsize do sleep(0); is important so that the Enter() method do not deadlock if the threads increment count beyong fsize... You can download my enhanced scalable Anderson Lock from: http://pages.videotron.com/aminer/ Thank you, Amine Moulay Ramdane
