Specifying JES2 initialization statements and commands involves using numeric values, alphabetic values, uppercase or lowercase characters, or blanks.

• You must code written uppercase operands as they appear in the syntax diagrams. Also, punctuation such as commas, parentheses, and single quotation marks are not metasymbols; if present in the syntax diagrams they must be coded. Parameters shown in lowercase are not to be coded as written; they denote variables that are explained in the description of the particular parameter for the initialization statement or command.
• You must code numbers and uppercase letters exactly as shown.
• You must substitute specific information or specific values for lowercase letters, which represent variables.
• You can use blanks anywhere within an initialization statement or command, but you need not use any blanks.
