Syntax Conventions in the ABAP Keyword Documentation
The ABAP keyword documentation uses the following syntax conventions:
ABAP words are displayed in uppercase letters.
Example:
APPEND, NON-UNIQUE, INTO
Operands are displayed in lowercase letters.
Example:
dobj, dbtab
Parts of statements whose syntax diagrams are shown in another place are
displayed as pseudo syntax.
Example:
selscreen_options, list_options
Periods, commas, colons, and parentheses are displayed as normal. They
are part of the ABAP syntax.
Example:
. : , ()
Operators are displayed as normal. They are part of the ABAP syntax.
Example:
+, -, *, /
Parts of statements that are optional are displayed in square brackets
[ ] . A list of parts of statements in square brackets means that
some or all of the parts can be used. If at least one part must be used,
this is noted in the text. Square brackets are not a part of ABAP
syntax. (Exception: table expressions ).
Example: :
[NO-GROUPING] [NO-SIGN] [NO-ZERO]
Vertical lines | between parts of statements mean that only one
of the parts listed within a statement can be used. A vertical line
always joins immediate neighbors. Lines are not a part of ABAP syntax.
(Exception: delimiters of string templates
).
Example:
DDMMYY | MMDDYY | YYMMDD
Curly brackets { } group together related parts of statements,
for example on the right or left of vertical lines. Curly brackets are
not part of ABAP syntax. (Exception:
embedded expressions in
string templates ).
Example:
{NO EDIT MASK}|{EDIT MASK mask}
A string of dots means that other parts of the statement can be included
at this point.
Example:
... AS CHECKBOX
