Restrictions
A symbolic name must not appear in both an EXTERNAL and an INTRINSIC statement in the same program unit.
The actual argument must be a specific name. Most generic names are also specific, but a few are not: IMAG, LOG, and LOG10.
A symbolic name can appear more than once in an INTRINSIC statement.In the FORTRAN 77 Standard, a symbolic name can appear only once in an INTRINSIC statement. @
Because they are in-line or generic, the following intrinsics cannot be passed as actual arguments:
