Using character conversion tables

A character conversion table is a table that converts one or more characters to alternative characters using hexadecimal encoding for the character sets. The character sets are defined in code pages. IBM® supplies these character conversion tables as members in SYS1.LINKLIB:

BPXFX100 (code page 00037 to and from 01047 for non-APL 3270)
BPXFX111 (null conversion)
BPXFX211 (code page 00037 to and from 01047 for APL 3270)
BPXFX311 (ASCII code page 008859 to and from 01047)

In particular, for the OMVS command, BPXFX100 is the default conversion table. As shipped, FSUMQ000 is an alias for BPXFX100. To change the OMVS default table, move the FSUMQ000 ALIAS to the new default, or rename the new default table to FSUMQ000.

Tip: Users who need different conversion tables can manually override the default table by using the CONVERT operand. In addition, the system programmer can write a REXX exec or CLIST to invoke the OMVS command with the proper table.

The source for these members is shipped in SYS1.SAMPLIB. If you need to change them, see Customizing code page conversion.
