The SNANLS API also allows applications to convert double-byte character stream (DBCS) EBCDIC-to-ANSI and DBCS ANSI-to-EBCDIC by leveraging another SNA Server API called TrnsDT. The TrnsDT API has its own mechanism to translate Far Eastern code pages using conversion table resource files (*.TBL files) that the setup program for Microsoft® SNA Server version 3.0 and later installs on the target PC.
In Microsoft® Windows® version 3.x and Microsoft® MS-DOS® environments where SNANLS is not supported, developers can use the TrnsDT API for supporting Far Eastern languages such as Japanese, Korean, and Chinese, and Windows code page support for single-byte conversions.
