Nlynx ETU400 manual About Translation Tables

About Translation Tables

The translation tables provided with ETU have three purposes. They:

•translate data from ASCII to EBCDIC or from EBCDIC to ASCII;

•specify whether the file being translated has a fixed or variable format;

•tell the host whether the micro involved in the translation is a DOS- based PC or a Mac.

Each translation table is stored as a member in a physical file. The DOS- based tables are in a physical file called TRANSLATE in the host library containing the ETU programs. The Mac translation tables are in a physical file called MACTAB in the same library.

The source for each table is also included with ETU. Each table is stored as a source member in a source file called TRANSSRC, also in the library containing the ETU programs. To modify a translation table, you will change one of the source members.

There are four tables for PC-DOS translations and three for the Mac translations. Each table and its function is described below in Table 8- 1.
