General Syntax Notation
Required Choice {| |}. Required choice indicators enclose multiple required syntax items. A
vertically aligned group of items enclosed in required choice indicators represents a list
of selections from which you must choose one or more, in any order, but cannot repeat
a selection.
Optional Choice [| |]. Optional choice indicators enclose multiple optional syntax items. A
vertically aligned group of items enclosed in optional choice indicators represents a list
of selections from which you can choose one or more, in any order, but cannot repeat
a selection.
| Vertical Line. A vertical line separates alternatives in a horizontal list that is enclosed in
brackets or braces. For example:
INSPECT { OFF | ON | SAVEABEND }
… Ellipsis. An ellipsis immediately following a pair of brackets or braces indicates that you
can repeat the enclosed sequence of syntax items any number of times. For example:
M address-1 [ , new-value ]...
[ - ] {0|1|2|3|4|5|6|7|8|9}...
An ellipsis immediately following a single syntax item indicates that you can repeat that
syntax item any number of times. For example:
"s-char..."
Punctuation. Parentheses, commas, semicolons, and other symbols not previously
described must be entered as shown. For example:
error := NEXTFILENAME ( file-name ) ;
LISTOPENS SU $process-name.#su-name
Quotation marks around a symbol such as a bracket or brace indicate the symbol is a
required character that you must enter as shown. For example:
"[" repetition-constant-list "]"
Item Spacing. Spaces shown between items are required unless one of the items is a
punctuation symbol such as a parenthesis or a comma. For example:
CALL STEPMOM ( process-id ) ;
If there is no space between two items, spaces are not permitted. In this example, no
spaces are permitted between the period and any other items:
$process-name.#su-name
Line Spacing. If the syntax of a command is too long to fit on a single line, each
continuation line is indented three spaces and is separated from the preceding line by
