Creating PDF translation tables

Creating PDF translation tables describes how to create a set of PDF translation tables.

Sample assembler modules are included in the ISP.SISPSAMP sample library (members ISROWNTT and ISRAPLTT). Module ISROWNTT contains a complete set of translation tables for an English 3278/3279 terminal, and module ISRAPLTT contains a complete set of translation tables for the 3278/3276 APL terminals. Use these as an example of what a completed module should look like. You can modify the samples to suit your requirements, supplying the desired values for each of the translation tables.

PDF uses these translation tables:

Valid data set name character translation table
Invalid data set name character translation table
Hexadecimal character translation table
Numeric character translation table
Alphanumeric character translation table
Edit terminal output character translation table
Generic string character translation table
Generic string special character translation table
Uppercase character translation table
Lowercase character translation table.

The sample Assembler module includes all of these translation tables. Each translation table consists of 32 consecutive DC statements, where each DC statement consists of eight hexadecimal values. You are free to supply the desired 256 hexadecimal values that comprise each of the translation tables. The only exception to this is the generic string character translation table that consists of 32 consecutive DC statements, each consisting of one hexadecimal value. This table should not be modified. The address of each table is located at the start of the Assembler module. If a table is not used, the address for that table is set to 0 (for example: EDIP DC A(0)).
