>>>I need to go to the end of file (TXT) and then, skip -410 positions, and then write something new.

>>>The code that always (until now) worked fine is below:
>>>

>>>nFile = FOpen("FILE.TXT",12)
>>>FSeek(nFile,-410,2)
>>>FPuts(nFile, "MY NEW TEXT HERE")
>>>

>>>
>>>Now, maybe after update my VFP9 to SP1, I have to do that:
>>>

>>>nFile = FOpen("FILE.TXT",12)
>>>FSeek(nFile,0,2)
>>>FSeek(nFile,-410,1)
>>>FPuts(nFile, "MY NEW TEXT HERE")
