| uppercase, bold
|
Syntax elements appearing in uppercase
and bold font are Adabas keywords. When specified, these keywords must be
entered exactly as shown.
|
The syntax elements ADADBS, CHANGE, and FILE are Adabas
keywords.
|
| lowercase, italic, normal font
|
Syntax elements appearing in lowercase
and normal, italic font identify items that you must supply.
|
The syntax element
file-number identifies and describes the kind of
value you must supply. In this instance, you must supply the number of the file
affected by the ADADBS CHANGE operation.
|
| mixed case, normal font
|
Syntax elements appearing in mixed case
and normal font (not bold or italic) identify items established by other Adabas
control statements. This notation is usually used to identify how default
values are determined for some parameters in Adabas syntax.
|
The syntax element
"ADARUN-device" indicates that the device type
identified by the ADARUN DEVICE parameter will be used if a different device
type is not specified. The literal "ADARUN-device"
should not be specified for the SORTDEV parameter.
|
| underlining
|
Underlining is used for two purposes:
-
To identify default values, wherever appropriate.
Otherwise, the defaults are explained in the accompanying parameter
descriptions.
-
To identify the short form of a keyword.
|
In the example above, 4000 is the default that will be
used for the LRECL parameter if no other record buffer length is specified.
In the example above, the short version of the DEVICE
parameter is DE.
|
| vertical bars (|)
|
Vertical bars are used to separate
mutually exclusive choices.
Note:
In more complex syntax involving the use of large
brackets or braces, mutually exclusive choices are stacked
instead.
|
In the example above, you must select RESTRUCTUREF or
REF for this ADAORD function. There are no defaults.
|
| brackets ([ ])
|
Brackets are used to identify optional
elements. When multiple elements are stacked or separated by vertical bars
within brackets, only one of the elements may be supplied.
|
In this example, the SORTSEQ parameter and the MU, NU,
and STARTISN subparameters are optional.
Note:
Note that the mutually exclusive choices for the
SORTSEQ parameter are stacked.
|
| braces ({ })
|
Braces are used to identify required
elements. When multiple elements are stacked or separated by vertical bars
within braces, one and only one of the elements must be supplied.
|
In this example, either the SUSPEND or RESUME parameter
is required.
|
| indentation
|
Indentation is used to identify
subparameters of a parameter.
|
In this example, TTSYN and TRESUME are subparameters of
the SUSPEND parameter.
|
| ellipsis (...)
|
Ellipses are used to identify elements
that can be repeated. If the term preceding the ellipsis is an expression
enclosed in square brackets or braces, the ellipsis applies to the entire
bracketed expression.
|
In this example, the FIELD parameter can be repeated. In
addition, more than one option can be associated with a field.
|
| other punctuation and symbols
|
All other punctuation and symbols must
be entered exactly as shown.
|
In this example, the single quotation marks must be
specified around the field definitions and their associated options. In
addition, options must be separated by commas.
