Syntax Conventions 

The conventions for syntax statements in this documentation are as follows:

Key

Definition

STATEMENT

Keywords and options of statements are uppercase.

<variable>

Variables, or words that stand for values that you fill in, are in angle brackets. Do not include the angle brackets in the value you use (exception: field symbols).

[]

Square brackets indicate that you can use none, one, or more of the enclosed options. Do not include the brackets in your option.

|

A bar between two options indicates that you can use either one or the other of the options.

()

Parentheses are to be typed as part of the command.

,

The comma means you may choose as many of the options shown as you like, separating your choices with commas. The commas are part of the syntax.

<f1> <f 2>

Variables with indices mean that you can list as many variables as you like. They must be separated with the same symbol as the first two.

.......

Dots mean that you can put anything here that is allowed in the context.

 

In syntax statements, keywords are in upper case, variables are in angle brackets. You can disregard case when you type keywords in your program. WRITE is the same as Write is the same as write.
