Using ASCII-EBCDIC Tables

Most ClearPath NX, ClearPath LX, and A Series hosts communicate using EBCDIC characters, while most PCs communicate using ASCII characters. To ensure that the host and clients can communicate, Presentation Builder includes a file, Asctoebc.aet, that contains internal default values to convert specific characters from one format to the other. These defaults are based on the U.S. English ASCII character set. If your computer uses a different character set, you might need to create and use a different ASCII-EBCDIC table.

To create a new ASCII-EBCDIC translation table
  1. In a text editor such as Notepad, open the existing ASCII-EBCDIC table file (filename.aet).

    This file is located in the Attachmate\EAI\PresentationDesigner\ScreenConnectors\UnisysConfig\exlat directory.

  2. Make changes as required to each section of the file:
    To change a value
    Type the appropriate value in the
    The client sends to the host [AsciiToEbcdic] section.
    The host sends to the client [EbcdicToAscii] section.
  3. Using a .aet filename extension, save the file in the Attachmate\EAI\PresentationDesigner\ScreenConnectors\UnisysConfig\exlat directory.

    To prevent overwriting your changes when you upgrade, you should always save modified tables with a new name.

  4. If the Presentation Builder Runtime Service is installed on a different computer than the Presentation Designer, copy the new file to the same directory on the Runtime Service computer.
