ABL provides built-in data types, built-in class data types, and user-defined class data
types. References to built-in data types follow these rules:
- Like most other keywords, references to specific built-in data types appear in all
UPPERCASE, using a font that is appropriate to the context. No uppercase
reference ever includes or implies any data type other than itself.
- Wherever integer appears, this is a reference to the INTEGER
or INT64 data type.
- Wherever character appears, this is a reference to the
CHARACTER, LONGCHAR, or CLOB data
type.
- Wherever decimal appears, this is a reference to the DECIMAL
data type.
- Wherever numeric appears, this is a reference to the
INTEGER, INT64, or DECIMAL data
type.
References to built-in class data types appear in mixed case with initial caps, for example,
Progress.Lang.Object. References to user-defined class data types appear in
mixed case, as specified for a given application example.
