Statements and attributes

This section 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.

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, Fortran 2008 begins DO CONCURRENT Fortran 2008 ends , or DO WHILE construct. The executable statements, specification statements, and terminal statements are marked with "√".

Assignment and pointer assignment statements are discussed in Expressions and assignment. Both statements are executable and can serve as terminal statements.
