ECO KIT SUMMARY:
An ECO kit exists for Fortran V4.1 on DIGITAL UNIX V3.0 through V4.0.
This kit addresses the following problems:
The following changes and corrections were made to the DIGITAL Fortran 90
compiler in FORTAUE02041:
o Cray pointees that were being allocated statically are
now correctly given no storage class.
o Using assumed shape array within a contained routine no
longer produces an internal compiler error.
o An error message is now given for invalid keyword values
given for an I/O statement's keyword.
o Declarations of the type "character, allocatable ::
field*7(:)", in which the array shape specifier comes
after the length specification in a deferred-shape
character array no longer produces an internal compiler
error.

constructor, if a character scalar is supplied to an
character array component, every elements of the array
is assigned with the character scalar value.
o The MVBITS intrinsic now gives correct result if its 4th
argument is a non-lowerbound subscripted array element.
o Reference of a character function, where the length
of its return value is dependent on one or more of
its arguments, no longer produces an internal compiler
error.
o Pointer assignment should now work properly when the
target is a component of an allocatable array with a
lower bound different of 1.

error.
