Some language features, considered redundant in FORTRAN 77, are not
included in Fortran 95. However, they are still fully supported by
DIGITAL Fortran:
ASSIGN and assigned GO TO statements
Assigned FORMAT specifier
Branching to an END IF statement from outside its IF block
H edit descriptor
PAUSE statement
Real and double precision DO control variables and DO loop
control expressions
For suggested methods to achieve the functionality of these
features, see Section A.1.
