How to Read the Syntax Diagrams

The following rules apply to the syntax diagrams used in this book:

• Read the syntax diagrams from left to right, from top to bottom, following the path of the line.

  The >>--- symbol indicates the beginning of a statement.

  The ---> symbol indicates that the statement syntax is continued on the next line.

  The >--- symbol indicates that a statement is continued from the previous line.

  The --->< symbol indicates the end of a statement.

  Diagrams of syntactical units other than complete statements start with the >--- symbol and end with the ---> symbol.

• Keywords, their allowable synonyms, and reserved parameters, are either shown in uppercase or lowercase, depending on whether the platform is for MVS, OS/2, or UNIX products. These items must be entered exactly as shown. Variables appear in lowercase italics (for example, column-name). They represent user-defined parameters or suboptions.

  When entering commands, parameters and keywords must be separated by at least one blank if there is no intervening punctuation.

• Enter punctuation marks (slashes, commas, periods, parentheses, quotation marks, equal signs) and numbers exactly as given.

• Footnotes are shown by a number in parentheses, for example, (1).

• Required items appear on the horizontal line (the main path).

  >>-required_item-----------------------------------------------><
   
  

• Optional items appear below the main path.

  >>-required_item--+---------------+----------------------------><
                    '-optional_item-'
   
  

• If you can choose from two or more items, they appear vertically, in a stack.

  If you must choose one of the items, one item of the stack appears on the main path.

  >>-required_item--+-required_choice1-+-------------------------><
                    '-required_choice2-'
   
  

  If choosing one of the items is optional, the entire stack appears below the main path.

  >>-required_item--+------------------+-------------------------><
                    +-optional_choice1-+
                    '-optional_choice2-'
