There are a number of ways to get information from III to a file your computer. The best method depends on the system permissions and software you have as well as the size of the file. Unless you are the system administrator or your library has a policy of assigning broad permissions, some options may not be available to you. Screen capture is generally the best method when available. FTS is good for large files but it requires you to set up an ftp server on your machine.
Email is good for small files but awkward with files containing thousands of records.
Depending on your telnet client, you may also be able to set up a printer that prints to a file instead of an LPT port. Transferring Information To III From A Local Machine Records and tables in III can only be accessed through the user interface, so any application that sends information to III must act as if it were a person typing very rapidly. This means that the application must be able to determine what screen it is on so that it sends information to the correct screens when III expects it. The best way to accomplish this is to use a telnet client that contains a macro language. Virtually all telnet clients support scripting on some level.
