Another type
of DBCS encoding exists on mainframe systems, which combine DBCS support
with the 3270-style data stream. Each DBCS character string is surrounded
by escape codes called shift
out/shift in, or SO/SI. These
codes originated from the need for the old-style printers to shift
out from the EBCDIC character set, to the DBCS character set. The
major manufacturers have different encodings for SO/SI; some manufacturers
pad DBCS code with one byte of shift code information while others
pad the DBCS code with two bytes of shift code information. These
differences can cause problems in reading DBCS information about mainframes.
PCs, minicomputers,
and workstations do not have SO/SI but have their own types of DBCS
encodings that differ from manufacturer to manufacturer. SAS has
several formats and informats that can read DBCS on SO/SI systems:
