Question and a Holiday thanks to Everyone

First let me extend a warm holiday thanks to everyone on the list, from Bob 
Cozzi, to Scott Klement and all the rest of you; I have learned far more in 
the past year than I could have possibly imagined.  I know at times that I 
have asked some stupid questions and a few of you have even told me so :) 
However, I am far better at what I do because of this list and each of you 
have contributed more than your fair share.

May all of you have a happy and joyous holiday season, whether you are 
celebrating Christmas, Chanukah, or the myriad of other celebrations that 
occur at this time of year.

Now, onto my question.  I have several programs that create temp files for 
purposes of migrating and mining data.  Although I do not see it happening 
very often, there is the possiblity that two users could inavertently run 
into each other.  Is there an easy way for me to do the following:

1. Determine if there is a record lock currently applied to a file and if 
so, who has that lock.

2. Lock a file so that nobody else can make changes to it while the program
(s) is running.

I have not worked with file locks to this point so any helpful suggestions 
would be appreciated.
