EXTERNAL is used to declare a subprogram name in a program segment that passes that subprogram name as an argument to another subprogram. There is no double-precision complex type in standard Fortran 77, but many compilers provide one (at the expense of portability). 10

WebIntrinsic functions that are Sun extensions of the ANSI FORTRAN 77 standard are marked with @. Intrinsic functions have generic and specific names when they accept arguments of more than one data type. In general, the generic name returns a value with the same data type as its argument.
