8.6.5 Statement Labels

(Corresponds to Section 3.4 of ANSI X3.9-1978 FORTRAN 77.)

A statement separated from its predecessor via a semicolon may be labeled as follows:

• The semicolon is followed by the label for the statement, which in turn follows the label.
• The label must be no more than five digits in length.
• The first digit of the label for the statement is not the first non-space character on a line. Otherwise, that character is treated as a continuation character.

A statement may have only one label defined for it.
