Abhijit. On point 3, EasyLanguage 2000 certainly had File, FileAppend
and FileDelete statements and locking could be avoided with some
workarounds especially if there is only one server and one client.
Having said that though, you make a compelling argument for email as a
robust and elegant solution to the problem.
Interesting thread.

John, it's not hocus pocus.
1) It's much simpler than it sounds. Less than a page of code
2) This will be a socket communication between TS & your program. VERY
robust
3) TS sends email. I am not sure if it writes text files. If it does,
say "file locking"
4) File based interface would be a order of magnitude slower than socket
communication
It's about as easy as this
try {
serverSocket = new ServerSocket(25);
} catch (IOException e) { /* error handling */ }
try {
clientSocket = serverSocket.accept();
/* Got the mail here. Parse it. Trade it */
} catch (IOException e) { /* error handling */ }
Just to demonstrate how easy it is for someone to implement this.
Thanks,
Abhijit
