This chapter provides an alphabetical reference to all XL Fortran statements. The section for each statement is organized to help you readily access the syntax and rules, and points to the structure and uses of the statement in Part 2, Concepts and Elements.
The following table lists the statements, and shows which ones are executable, which ones are specification_part statements, and which ones can be used as the terminal statement of a DO or DO WHILE construct.
