Adding translation tables for extended code page support

You can provide support for additional code pages by creating or modifying translation tables using the sample assembler module ISPEXCP in the ISP.SISPSAMP library.

Any translation tables that are added must be named ISPnnnnn, where nnnnn is the CCSID, and must be a CCSID defined in the Character Data Representation Architecture Registry. This CCSID must be different from any of the supported CCSIDs. The translation tables should include code points X'40' through X'FE'.

Table 1 and Table 2 show examples of the "To" and "From" translation tables needed to translate characters between CCSID 00500 and CCSID 00037.
