The descriptions of the different DBH start statements and options are all structured in the same way. There is an entry for each start statement or option and in each case, the name of the statement or option is the entry's heading.
Each entry consists of several parts.
Sections that are not relevant to a specific statement or option are not included. The most important sections are described overleaf.
Name of the start statement or option
Brief description
Definition
This section indicates whether the entry describes a DBH start statement or an option.
In the case of start statements, you will see the text “The n-th DBH start statement” here. This means that you can immediately identify that this is a description of a start statement and what position this start statement occupies in the input sequence.
In the case of DBH options, the text will be either “A higher-level DBH option” or “A lowerlevel DBH option of higher-level dbh option”.
This means that you can immediately identify which category the option belongs to and which option (if any) is superordinate to it.
Function
This section provides a detailed description of the statement or option. As well as telling you what the statement or option does, it provides other important information and explanations relating to it.
It is followed by a syntax diagram.

Operands
This section contains explanations of the various operands. The operands are dealt with in the order in which they occur in the syntax diagram.
Subheading
Sections containing additional information on the statement or option may follow the operand descriptions.
Special feature of the descriptions of higher-level DBH options
The SDF syntax diagrams in the descriptions of higher-level DBH options differ from those in the other descriptions.
The following example shows the SDF syntax diagram of the higher-level DBH option ADMINISTRATION.
ADMINISTRATION | ||||||||||||||||||||||||
| ||||||||||||||||||||||||
Unlike the other syntax diagrams, the line *PARAMETERS(...) with the lines following it is contained here. All the DBH options which are at a lower level than the DBH option ADMINISTRATION are listed as operands here. Only the default operand values are given. The complete description of all permitted operand values is not provided here.
The list of all the associated lower-level DBH options with their default values is intended to facilitate orientation. If you select *PARAMETERS(...) rather than *STD for a higher-level option, you have to take the listed DBH options with all their operands into consideration.
