The file would be arriving FTP to a given location at a given time(s) each 
day.  A program is needed that would do the following:

1. Wait for the arrival of a file that is expected to come to a given server 
at an approximate  time. 

2. Monitor the FTP process by testing for increasing file size.  When the 
file stops growing for a safe amount of time (I am just using a minute for a 
"wait" period.  Perhaps this is too long) the file is then available for 
operations.

Don't bother.  Just   wondered if anyone has a similar process to compare and 
save time.
