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 ªOBº.

1. The start-of-record indicator

This is always the letter ªS.º

2. The record-type indicator

This is a ª2,º ª3,º or ª4.º 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.
