| 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.
