SNA 3-131 Modifying EBCDIC/ASCII Translation Table to Support Printing of
Foreign Language Characters
APPLIES TO: NetWare 3270 Workstation
SUPERSEDES: a slight revision of 3-35
DATE: December 3, 1990
Novell control programs that support 3287 host printer emulation use an
EBCDIC/ASCII Translation Table File (NVLPSTD1.XLT). Its purpose is to
convert EBCDIC characters in the host printer datastream to printable ASCII
characters. Novell provides a file that will properly translate only the
standard 96- character set used in the U.S. For foreign language users, it
is necessary to create alternative translation tables to support the
printing of desired foreign language characters.
The provided translation table (NVLPSTD1.XLT) consists of a single 256-byte
record. Each ASCII value is located at an offset (displacement) in this
table equal to the value of the corresponding EBCDIC character. The table
can be modified by using the DOS DEBUG command. The ENTER subcommand (e)
can be used to modify those locations requiring change. When the changes
are complete, WRITE subcommand (w) can be used to rewrite the translation
file.
Note that DEBUG presumes a beginning address of 100. Thus 100 must be
added to the EBCDIC value whose ASCII equivalent is to be entered.
The modified file can (and should) be named differently to avoid confusion.
The name must be of the form NovellPxxxx.XLT where xxxx can be any
alphanumeric character string. The affected control program must then be
recustomized. Item 6 in the Printer Customization panel must be changed to
reflect the changed file name.
For information on the various EBCDIC values for foreign languages, your
attention is directed to Chapter 11 of IBM publication GA27-2837 (IBM 3270
Information Display System Character Set Reference).
