NOTATION

DESCRIPTION

nonitalics

Words in syntax statements that are not in italics must

 

 

be entered exactly as shown. Punctuation characters

 

 

other than brackets, braces, and ellipses must also be

 

 

entered exactly as shown. For example:

 

 

EXIT;

italics

Words in syntax statements that are in italics denote a

 

 

parameter that must be replaced by a usersupplied

 

 

variable. For example:

 

 

CLOSE filename

[ ]

An element inside brackets in a syntax statement is

 

 

optional. Several elements stacked inside brackets

 

 

means the user may select any one or none of these

 

 

elements. For example:

 

 

 

 

 

 

 

 

 

A

User may select A or B or neither.

 

 

 

B

 

 

 

 

{ }

 

 

 

 

 

When several elements are stacked within braces in a

 

 

syntax statement, the user must select one of those

 

 

elements. For example:

 

 

 

A

 

 

 

 

B User must select A or B or C.

 

 

 

C

 

...

A horizontal ellipsis in a syntax statement indicates

 

 

that a previous element may be repeated. For

 

 

example:

 

 

 

[,itemname]...;

 

 

In addition, vertical and horizontal ellipses may be

 

 

used in examples to indicate that portions of the

 

 

example have been omitted.

 

 

A shaded delimiter preceding a parameter in a syntax

,

 

 

 

statement indicates that the delimiter must be

supplied whenever (a) that parameter is included or

(b) that parameter is omitted and any other parameter that follows is included. For example:

itema[,itemb][,itemc] means that the following are allowed:

itema itema,itemb itema,itemb,itemc itema,,itemc
