General Expression Positions

General expression positions are reader positions in which suitable data objects, constructor expressions, table expressions, calculation expressions, predefined functions, or functional methods and method chainings can be specified. The following general expression positions exist:

  • Operand of the statement CASE,
  • Work area wa of the statements
  • Expression exp for dynamic sorts in the case of

The type restrictions defined by the operand type apply in the operand positions. For example, no numeric functions can be specified in a bit expression.

Other versions: 7.31 | 7.40 | 7.54


  • Specifying functional methods as actual parameters of methods enables the nesting of method calls in an operand position.

  • The three types of calculation expression can be executed as operands of relational expressions, but they cannot be mixed in one calculation expression.
