20.1 Service requests vs FDSERVER

     The difference between a service request and a FDSERVER request
     is that they are processed while two systems are connected. This
     has the drawback of being slightly more expensive, but it offers
     a much greater flexibility than the FDSERVER function.

     Consider this. You have a program on your system that allows
     people to search for data in a database of files and then get a
     list of all the new files, you have named the service request
     WHATSNEW.

     Your system receives a file request for WHATSNEW and FD runs the
     program SEARCH.EXE, defined as the program to run for WHATSNEW.
     When SEARCH terminates, FD will send the file NEWFILES.LST,
     created by SEARCH, to the remote system.
