Explain Multi-byte Support For Pb?

1.	Explain Multi-byte Support For Pb?
Answer» PB 8 supports both ANSI and double-byte character sets (DBCS); any PB8 application runs in a DBCS environment. In a DBCS environment 1 character = 2 bytes as opposed to 1 byte in an ANSI environment. For example we MAY need to change the width of a column of type char (40) to char (80). The wide version of the Len () function (called Lenw ()) should be used since the former returns the number of bytes while the latter returns the number of characters. PowerBuilder can access UNICODE DATA in an ASE 12.5 Unicode database or in Unicode columns in ASE 12.5. PowerBuilder converts between double-byte character SET (DBCS) data and Unicode automatically, provided that the Locale parameter is set with DBCS values. For example, the Locale DBParm should be set to chs or cht.
