DATA TKX/2HKX/
TKX is a double real number.

DATAis an old-fashioned way of initialising a variable and2HKXis an example of an (even more) old-fashioned Fortran feature called Hollerith data. In this case2HKXis a way of expressing the stringKXfor a language without character or string data types; Fortran before FORTRAN77 was such a language. So what you have is a way of storing the 2 character stringKXin a variable declared to be of numeric (in your caseDOUBLE PRECISION) type.Hollerith data was dropped from the language in the 77 standard but, like all good (wink) things, has lingered long past its use-by date.
