DBCS Literals

There is a fourth type of literal in addition to the nonnumeric, numeric and national literals described in the section Literals, the DBCS literal.

A DBCS literal is a character-string delimited at both ends by quotation marks or apostrophes, with the beginning delimiter preceded by a "G". It can consist of any characters in the computer's DBCS character set. It can be up to 28 DBCS characters in length. It cannot be continued across lines.

Whether quotation marks or apostrophes are used, the presence of that delimiter within a DBCS literal can be represented by two contiguous occurrences. The presence of the character that is not serving as the delimiter is represented by a single occurrence. The value of a DBCS literal in the object program is the string of characters itself, except:

  1. The initial G and the delimiters are excluded, and
  2. Each embedded pair of contiguous delimiter characters represents a single character.
