General Syntax Items

Input strings can contain the following characters:

• Letters a through z

• Numbers 0 through 9

• Period and underscore

If you use any other characters, you need to use double-quotation marks around the characters.

A single statement can be placed on its own line and be terminated with a semicolon. Multiple statements are placed within braces. A list of items must be separated by commas and enclosed in double-quotation marks.
