Block-letter tables, APSUBTBL

The block-letter tables, APSUBTBL, consist of:

• A translate table
• An index table
• A performance block-letter table
• A default block-letter table

You can use APSUBTBL to create new block letters, add new block letters, and change existing block letters. The default tables produce block characters from the following input:

• Uppercase letters, A–Z
• Symbols, $, #, and @
• Numerals, 0–9
• Lowercase letters, a–z, which are translated to uppercase letters for printing
• Superscript EBCDIC numerals, which are translated to numerals (0–9) for printing
• All other characters, which are translated to blanks

PSF provides the assembly-language source code in SYS1.SAMPLIB for the block-letter tables, APSUBTBL. You can modify, assemble, and install, or link-edit with the replace option, APSUBTBL to create your own block-letter tables.

If installation separator page Exit 1, Exit 2, or Exit 3 is installed, APSUBTBL must also be installed. If APSUBTBL is not installed, PSF issues message APS959I, and processing continues without the separator page exits.
