Each character in the double-byte character set (DBCS) is stored in 2 bytes. When the GRAPHIC compiler option is in effect, some source language elements can be written using DBCS and SBCS characters. In particular, you can use DBCS characters in the source program in following places:
However INCLUDE file names and the TITLE option of FETCH statements must be in SBCS.
On the z/OS platform, each string of DBCS characters must be immediately enclosed in shift codes, but shift codes are neither required nor accepted on the other platforms supported by the compiler. In the examples that follow, these shift codes will be included, but they must be omitted on all platforms other than z/OS.
