XES COMMAND LANGUAGE MODE
• The table load terminator, which is the XL part of the
command. It signals to the printer that all data records have
been sent.
More about the table data record
The data record tells the printer how a new table is to translate
incoming data. The format of the table data is very specific and
must be followed carefully. The data may be grouped either in
one long record or in a series of records.
Each record consists of six elements:
1
. The start-of-record indicator
2. The record-type indicator
3. Byte count
4. Load address
5. Table entries
6. Record terminator.
Note: In the descriptions that follow, hexadecimal values are
expressed as two alphanumeric characters followed by H. For
example, if a field contains a hexadecimal value with a length of
two bytes, the field will consist of the two characters used to
represent that value as typed at the keyboard. Where
alphanumeric characters are indicated, they are enclosed in
double quotes, for example “OB”.
1. The start-of-record indicator
This is always the letter “S.”
2. The record-type indicator
This is a “2,” “3,” or “4.” Each number has a significance:
• 2 alters the U.S. English table for use with any non-ISO font
when language H has been specified. (Language H is
specified automatically upon completion of the Table
download.)
• 3 and 4 alter only the ISO table. The ISO table serves as a
base for both ASCII and EBCDIC multinational mappings.
