That is, more than one choice can be specified, with eachchoice separated by a comma.Double-byte character set notationDouble-byte character set (DBCS) characters in terms, expressions, characterstrings, and comments are delimited by shift-out and shift-in characters. In thismanual, the shift-out delimiter is represented pictorially by the < character, and theshift-in delimiter is represented pictorially by the > character. The EBCDIC codesfor the shift-out and shift-in delimiters are X'0E' and X'0F', respectively.The following figure summarizes the DBCS notation used throughout this manual.Character(s)Represents< Shift-out (SO)> Shift-in (SI)D1D2D3...

The dots separating the lettersrepresent the hexadecimal value X'42'. A double-byte character thatcontains the value of an EBCDIC ampersand or single quotation markin either byte is not recognized as a delimiter when enclosed by SOand SI.xii HLASM: V1R6 Language Ref
