"WebOutside of DATA statements, such constants are treated as the type required by the context. If a typeless constant is used with a binary operator, it gets the data type of the other operand (8.0 + '37'O). In DATA statements, such constants are treated as typeless binary, hexadecimal, or octal constants. Hollerith Constants @ " - Fortran binary data
