{ } Braces
A group of items enclosed in braces is a list from which you are required to choose one item.
The items in the list can be arranged either vertically, with aligned braces on each side of the
list, or horizontally, enclosed in a pair of braces and separated by vertical lines. For example:
LISTOPENS PROCESS { $appl-mgr-name }
{ $process-name }
ALLOWSU { ON | OFF }
| 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 [ , 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 typed
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 type 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 a blank line. This spacing distinguishes
items in a continuation line from items in a vertical list of selections. For example:
ALTER [ / OUT file-spec / ] LINE
[ , attribute-spec ]…
!i and !o
In procedure calls, the !i notation follows an input parameter (one that passes data to the called
procedure); the !o notation follows an output parameter (one that returns data to the calling
program). For example:
CALL CHECKRESIZESEGMENT ( segment-id !i
, error ) ; !o
