A group of items enclosed in brackets is a list from which you can choose one item or 
none. The items in the list can be arranged either vertically, with aligned brackets on 
each side of the list, or horizontally, enclosed in a pair of brackets and separated by 
vertical lines. For example: 
FC [ num ] 
 [ -num ] 
 [ text ] 
K [ X | D ] address 
{ } 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 ) ;
