When I open the file the order is set alright, maybe I have messed it somewhere along the code.

>In any case if you think WHILE is a problem simply use FOR instead. A FOR automatically rewinds to top, yes, but fox is clever enough to use index to find records for replacement with expressions like in your sample (I don't mean WHILE is a problem - whenever I saw WHILE fail it was my fault not Fox's).

Same I guess in my case, but the fun part is that it randomly fails.

That is an idea maybe the replacement is being done but somewhere else and I guess exact is off

>PS: You can use FOR and WHILE together in the same command.

REPLACE dbf.fld WITH .T. FOR dbf.id = m.id (WHILE ???)
