Literal Constants

A literal constant is an entity with a fixed value:

    12345      ! INTEGER
    1.0        ! REAL
    -6.6E-06   ! REAL: -6.6*10**(-6)
    .FALSE.    ! LOGICAL
    .TRUE.     ! LOGICAL
    "Mau'dib"  ! CHARACTER
    'Mau''dib' ! CHARACTER

Note,

• there are only two LOGICAL values;
• REAL s contain a decimal point, INTEGER s do not,
• REAL s have an exponential form
• character literals delimited by " and ';
• two occurrences of the delimiter inside a string produce one occurrence on output;
• there is only a finite range of values that numeric literals can take.
