Re: FTP problem

[Jim Langston <jlangston@xxxxxxxxxxxxxxxx>]

I can think of a few IDEAL solutions.

1. Rename the file.  Create the new one again, then get the rename file.  Or, 
better yet,
   if your program that writes to the file automatically creates it if it 
does't exit, just rename
   it, get it and delete it.  Easiest way if your program will recreate it.
2.  Exclusively lock the file when the FTP program wants to get it.  This would 
require
   a program to run somewhere that could actually lock a PC file.  Lock it, get 
it, delete
   it and recreate it.
3. Have the FTP program first PUT a file to the same directory as the file you 
want to
   get.  Have the program writing records to the file look for this file.  If 
that file exists, have
   the writing program wait til that file disappears.
4. Use ODBC to write to an AS/400 file instead of to a Novel file.  Then you 
don't have
   to use FTP at all.
5. Write a Client/Server pair to transfer records instead of ODBC.

There are many, many more ways I can think of.  If none of these help, let me 
know and
I'll throw a few more out.
