General File Transfer Settings

The settings made in the File Transfer area of session options affect only IBM 3270 proprietary file transfer methods. If you are not familiar with the file transfer protocols mentioned in this dialog, leave the defaults.

Note that to be able to transfer files to or from the connected host, the host must support IBM's IND$FILE Developed in the early 1980s to transfer files between an IBM mainframe and a system emulating a 3270 terminal. Variations of the IND$FILE program were developed for MVS/TSO,VM/CMS and CICS (both under MVS and DOS/VSE). transfer protocol and you must be at a screen where you can type host commands.

To access this dialog, select Options/Session menu item and scroll to File Transfer. Click on the File transfer icon to see these options.

Program Name - This is the name of the File Transfer Program that the host to which the connection is made supports. The default is IND$FILE. Only change this if your system administrator instructed you to do so.
Mainframe Code Page Code pages define the symbols used for translation between ASCII and EBCDIC characters. - The code page to use for the ASCII ASCII (American Standard Code for Information Interchange) is the most common format for text files in computers and on the Internet. In an ASCII file, each alphabetic, numeric, or special character is represented with a 7-bit binary number (a string of seven 0s or 1s). 128 possible characters are defined. ASCII was developed by the American National Standards Institute (ANSI). /EBCDIC EBCDIC is an extension to 8 bits of BCDIC (Binary Coded Decimal Interchange Code), an earlier 6-bit character set used on IBM computers. EBCDIC was used on the successful System/360. translation during the transfer. Use the drop down menu to select the appropriate Mainframe Code Page.
Host Type - Choose the mainframe Host Type where the file transfer will originate by selecting one of the radio buttons for CMS, TSO or CICS. The default is CMS.
PC Code Page - Choose a PC Code Page by selecting either the Windows or the DOS radio button. Windows uses ISO8859-1 code page standards, and DOS uses IBM CP850 PC/DOS code page standards.
Transfer Mode - The Transfer Mode should be chosen according to the terminal type and host system you connect to. The default is WSF (Write Structured Field), which generally achieves a better transfer rate than screen images. Screen Images file transfer uses screen images and special 3270 attribute bytes to transfer data.
WSF Buffer Size - Only affects WSF file transfers. In general, the larger the buffer size the faster the transfer rate. However, the maximum buffer size may already have been set by VTAM VTAM (Virtual Telecommunications Access Method) is an IBM application program interface (API) for communicating with telecommunication devices and their users. VTAM was the first IBM program to allow programmers to deal with devices as "logical units" without having to understand the details of line protocol and device operation. Prior to VTAM, programmers used IBM's Basic Telecommunications Access Method (BTAM) to communicate with devices that used the binary synchronous (BSC) and start-stop line protocols. or a VTAM session manager. The default buffer size is 8K.
Completion Options - You can choose to have the transfer progress dialog closed automatically when the transfer is complete, or to leave it open and display any status or error message. If you choose to have the messages displayed, you will need to manually close the transfer dialog.
