Operand syntax

This section contains the precise syntactic definition of the various variable operands which occur in EDT statements. An operand's name always makes it possible to identify its particular syntactic definition. Any special semantic considerations or restrictions within the context of the particular statement in question are indicated in the operand descriptions in the detailed statement descriptions.

All the operand types are defined in the following sections. These operand types are used as operand names in the detailed statement descriptions. If syntactically equivalent operands occur at various positions in a statement description then they are differentiated by appending a sequential number. A definition is provided only for the basic names of any such operands.

The following description of the operand syntax is subdivided into thematically linked sections. Within the sections, the descriptions are organized in such a way that, if possible, each operand type is defined before it is used for the first time. The following alphabetically ordered overview will help readers find the particular definitions they require.
