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 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
|
Mixed case is used for two purposes:
-
To identify the short form of a keyword. The short
form is the part in uppercase; the lowercase parts of the statement, command,
or parameter is not necessary.
Note: If a lowercase part appears in italics, it
represents a value you must supply; in this case the syntax would not identify
a short form.
-
Some values of parameters are taken from values of
other parameters. In these cases, the name of the parameter referenced for the
value appears in uppercase
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.
|
-
In the example above, the minimum form of the
parameter is DE.
However, in the following example, the
nn identifies a value you must supply. There is no
minimum form of the parameter.
-
The syntax element
"ADARUN-device" indicates that the device type
identified by the ADARUN DEVICE parameter will be used as a default if a
different device type is not specified. The literal
"ADARUN-device" should not be specified for
the SORTDEV parameter.
|
underlining
|
Underlined text identifies default values, wherever
appropriate. Otherwise, the defaults are explained in the accompanying
parameter descriptions.
|
In the example above, 4000 is the default that will be
used for the LRECL parameter if no other record buffer length is specified.
|
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. If SUSPEND is specified, either or both TTSYN or TRESUME may be
specified.
|
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.
