S/390 Host Double-Byte Character Set Emulation

HCON allows emulation for a double-byte character set (DBCS) (Japanese, Korean, and Traditional Chinese) display or a printer attached to a S/390 mainframe host. DBCS operation provides one- and two-byte character set support.

A DBCS emulation session operates in a window environment that supports DBCS data input and output operations. Printer sessions need a printer with capability to handle double-byte characters and field outlining.

A DBCS environment:

• Allows input of double-byte characters from the keyboard. The DBCS input method for Japan, Korea, and Traditional Chinese are provided by the operating system.
• Enables both display and printer sessions.
• Enables shift out (SO) or shift in (SI) mode with indicators on the screen.
• Allows selection of files for the genxlt command. The genxlt command generates custom translation tables for input/output and file transfer operations.
• Enables up- and downloading of files, including double-byte text, to and from the host using the fxfer command. The fxfer command provides the -l and -s flag options to support the two host code pages and to handle SO/SI. The fxfer command also provides the -b, -e, -k, -M, -c, -C, -J, and -N flags to support the host options of the APVUFILE file transfer program.

  Note: HLLAPI supports the DBCS environment.

With Japanese Language Support, a DBCS environment:

• Allows selection of the host code page for Japanese Language Support, either Japanese-English or Japanese katakana.
• Uses Alternate Viewing mode to switch the displayed character set, by a local key operation, between Japanese-English and Japanese katakana.

  Note: The Keyboard mode and Shift indicators, such as Alphanumeric and Japanese code page indicators, such as katakana or hiragana, are not displayed in the Operator Information Area (OIA). These indicators are displayed in the Status Area of an AIXTerm (the top right area of the window border).
