8.10.3 Construct Names

The GNU Fortran language supports construct names as defined by the Fortran 90 standard. These names are local to the program unit and are defined as follows:

construct-name: block-statement

Here, construct-name is the construct name itself; its definition is connoted by the single colon (`:'); and block-statement is an IF, DO, or SELECT CASE statement that begins a block.

A block that is given a construct name must also specify the same construct name in its termination statement:

END block construct-name

Here, block must be IF, DO, or SELECT, as appropriate.
