Comments FORTRAN uses two types of comments: comment lines and embedded comments. A comment line is denoted in a source file by a C, *, or ! in column 1, or by a blank line. A comment line is not a statement and does not affect the program in any way. Comment lines can be placed anywhere in a source file, including between lines of a continued statement. An exclamation point (!) following a statement on the same line indicates the beginning of an embedded comment, unless the exclamation point is contained in a character or Hollerith constant. The compiler ignores the exclamation point and any text following; that is, it treats them as blanks. This use of the exclamation point is an extension to the ANSI 77 standard. Exclamation points are not allowed in directive lines.
