If the installation has special conversion needs for single-byte data conversion, create the needed character conversion table by customizing an existing table:

1. Copy the assembler source for a table from SYS1.SAMPLIB into a new data set.
2. Edit the new data set to customize the table. SYS1.SAMPLIB(BPXFX100) shows the format of the conversion tables and, in its prolog, gives instructions and examples of how to edit a table.
3. Assemble the table.
4. Link-edit the table into a load module in SYS1.LINKLIB or another partitioned data set.

Each table is 1792 bytes long and contains the 8-bit codes that the system substitutes for characters in the input data set or file. Each table contains nine sections; you might have to change the data in all nine sections. Each member has a TO and a FROM subtable:

• The TO subtable is used to translate data from another code page to 01047.
• The FROM subtable is used to translate data from code page 01047 to another code page.
