From CCSID Fr ST To CCSID To ST GCCASN Def Method Number of Tables Local Table Name Tab Type Remarks
Note: This table is just a model used to describe the management-related aspects of accessing and selecting the appropriate conversion method and associated conversion table(s) for graphic character data conversion.
Note: Appendix B. "Conversion Methods" describes models for different conversion methods and associated conversion tables of different types.
00500 0 00037 0 1 1 Method 1 1 TT 00001 1 See Method 1 for SBCS and Figure 69.
00500 0 00037 0 2 0 Method x 1 TT 00005 1 This entry indicates that Method x and the table with the local name TT00005 should be used to convert as selected.
Note: Example of table re-use: note that the same conversion method and conversion table are used for three different pairs of CCSID in the following three entries. All the three "from" CCSIDs have the same CP element (CP 850). See Appendix C: CCSID Repository for access to a complete list of CCSIDs and their elements. Also, each conversion uses the same default criterion (round-trip integrity) used in creating the table TT00002.

Note: Example of marking a system default: the mark of 1 in the Def column makes the alternative 255 (below) the system installation default, instead of the alternative 1 (above), for the same pair of CCSIDs.

1 Other choice for TT00002;
Option number 255 says this table is customer defined. Different mismatch management criteria may have been used.
Note: Example of marking a system default: the mark of 1 in the Def column makes the entry with GCCASN value of 1 (2nd entry below) the installation default, instead of the entries with GCCASN values of 2 or 254 for the same pair of CCSIDs. Entries with GCCASN values of 1 and 2 use the same method, Method 2, but different conversion tables.

see Method 2 for Pure DBCS and Figure 55.

Note: Example of asymmetrical conversions: the following two entries show that the method and tables needed for conversion between the same pair of CCSIDs can be different depending on which CCSID is the "from" and which is the "to". The criterion used for the contents of the tables will determine whether symmetrical conversion of unmatched graphic characters is performed or not. The entries also show if the method used needs more than one table.
