Data Types

DCC natively supports data types including integer, decimal, double-precision decimal, logical, text, and large number data types. For constant expressions, DCC also has corresponding symbols to describe the data type of constants.

For numbers, just write them directly. Whether it’s a decimal will be intelligently judged based on the surrounding code. For text types, use full-width or half-width quotes (see examples in the Sensitivity chapter). For the four keywords true, false, TRUE, FALSE (case-insensitive), they are considered logical data (boolean type).
