NOTE: An OpenVMS saveset or PCSI installation file is stored
on the Internet in a self-expanding compressed file.
The name of the compressed file will be kit_name-dcx_vaxexe
for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha.
Once the file is copied to your system, it can be expanded
by typing RUN compressed_file. The resultant file will
be the OpenVMS saveset or PCSI installation file which
can be used to install the ECO.

ECO KIT SUMMARY:
An ECO kit exists for the Fortran Run-Time Library for OpenVMS Alpha
Systems V6.1 or higher. This kit addresses the following problems:
Problems Addressed in the FORRTLAVE01070 Kit:
o For Fortran 90 programs only, the default value of BLANK= for
preconnected units (not explicitly opened) has been changed from
'ZERO' to 'NULL'. This is consistent with the default on Digital
UNIX and other platforms, as well as with the default for
explicitly opened units and internal I/O. Fortran 77 programs
will continue to see BLANK='ZERO' as the default for preconnected
units and internal I/O.
o The RTL for F90 incorrectly failed to release previously
allocated memory when padding F90 input.
o The RTL would incorrectly go into an infinite loop when an
embedded NULL character value was found while performing a list
directed read operation.
o The RTL would incorrectly treat an end-of-record marker as a
value separator while performing a list-directed read operation.
o The RTL would not properly perform RTL I/O clean-up during an
unwind operation. This resulted in the user possibly receiving a
"recursive I/O operation" error if I/O was pending on the unit
before the unwind and then I/O was attempted after the unwind
operation.
o The RTL for F90 would incorrectly fail to return an End-of-record
error for certain non-advancing I/O operations. This occurred
when attempting to read into successive array elements while
running out of data.
Problems Addressed in the FORRTLAE01020 Kit:
NOTE: This ECO kit installs an updated version of the Fortran Run-Time
Library for OpenVMS Alpha systems which is used by both
DEC Fortran and DEC Fortran 90. This Run-Time library is
required for DEC Fortran 90 applications but not DEC Fortran
applications. However, it may be applied to systems running
DEC Fortran that are experiencing problems corrected by this ECO.
o Conversion of text to internal format failed to notice overflow.
o List-directed I/O to internal file lacked leading blank.
o INQUIRE across network fails.
o INQUIRE on NL: gives internal consistency failure.
o INQUIRE returns wrong CONVERT= values.
o BIG_ENDIAN processing of INTEGER*1/LOGICAL*1 gives wrong results.
o BIG_ENDIAN processing of VAX types lacks byte swap on IEEE type.
o VAXD/VAXG conversion of REAL*16 used IEEE_X rather than VAX_H.
o INTEGER*2 -1 record key value handled incorrectly.
o IEEE exception handling corrections.
o Run-time format syntax error results in internal error.
o Spurious characters in long output record.
o List-directed & G format now correctly format rounded values during
output conversion
o Access violation/segmentation fault with VFE.
o Backspace fails if rectyp=stream/lf/cr.
o Internal write with overlap produced unexpected results.
o BLOCKSIZE in OPEN not reflected in RAB$B_MBC field.
o Unformatted write access violates if psect=solitary.
o ENDDURREA with list-direct read of defaulted value at eor.
o Negative unit number gives INQUIRE and OPEN problems.
o MVBITS doesn't cross word/longword boundary.
o List-directed input cannot read complex value into real variable.
o Q edit descriptor should be ignored with output.
o INQUIRE NAME differs from VAX for non-existent file.
o Minor rounding changes per Fortran 90 standard.
o Performance improvement of unformatted, contiguous, direct I/O.
o Array bounds of run-time format are now ignored.
o Support for ISNAN and FP_CLASS intrinsic functions.
o Support for /CHECK=(OUTPUT_CONVERSION,FORMAT)
o Colon (":") format operator now works with zero implied iterations.
o Read w/INTEGER*2 key to remote file gives erroneous INVKEYSPE.
o I/O performance has been improved for unformatted I/O of arrays.
o Several minor problems with REAL*16 data have been corrected.
o Full IEEE exception handling has been improved.
o COMPLEX values displayed by list-directed and NAMELIST writes used
to begin a new record after the embedded "," if the REAL part would
fit in the current record but the entire value would not. This has
been fixed so that the entire value will be displayed in the next
record if the entire value won't fit in this record.
o Attempting to input -2**31 during a list-directed READ generated an
"input conversion" error.
o Double precision (T-floating) values are now formatted slightly
differently when written with list-directed output. The exponent
field has been increased from 2 to 3 characters, and the fraction
field has been decreased by one character.
o Unformatted, sequential read erroneously looks for ENDFILE marker.
o A $ format descriptor at the beginning of the FORMAT no longer gets
an INVARGFOR error.
o Namelist input of a 'T' or an 'F' where CHARACTER data was expected
no longer aborts the execution.
o The FORTRAN RTL did not output the secondary RMS status value for
some RMS errors.
o The FORTRAN RTL would output a extra blank line when the last item
was a zero trip implied do-loop (eg.; with n=1,0,"zero elements").
o The FORTRAN RTL would leave the NAM$L_RSA left pointing at a stale
stack temporary which did not allow users to get the value directly
from the NAM block.
o The FORTRAN RTL PAUSE didn't allow the debug command.
o Indexed organization files with a maximum record size(MRS) of 0
would incorrectly produce the IMPRECTOO or OUTSTAOVE error message.
o The DEC FORTRAN RTL would give a different IOSTAT value from the
VAX FORTRAN RTL for VFE values which are out of range.
o The DEC FORTRAN RTL VFE behavior no longer differs from the VAX
FORTRAN RTL behavior in terms of at what time during processing of
an I/O list the VFE is evaluated.
o The FORTRAN RTL incorrectly recognized repeated null values for
list-directed I/O.
o The FORTRAN RTL incorrectly produced a bugcheck error when given an
invalid file specification.
o The FORTRAN RTL incorrectly produced an input conversion error
(INPCONERR) for some small integer conversions.
o The RTL now correctly checks the range of VFE values. Previously,
certain out-of-range values could cause unpredictable results.
INSTALLATION NOTES:
This ECO kit is installed using the POLYCENTER Software Installation
(PCSI) utility. The following is an example PCSI command that can be
used to install this ECO kit:
$ PRODUCT INSTALL FORRTL/SOURCE=[location of the .PCSI file]
NOTE: The PCSI kit file name is DEC-AXPVMS-FORRTL-V0700-2-1.PCSI.
Respond to the prompts as directed by the Digital Fortran Installation
Guide.
The system/cluster does not need to be rebooted after this kit is
installed. However, if this kit is being installed on a VMScluster
system, the following command should be performed on all other nodes of
the VMScluster after the installation of this ECO.
$ INSTALL REPLACE SYS$LIBRARY:DEC$FORRTL.EXE
Read the release notes, which are provided in the following file:
SYS$HELP:FORRTL.RELEASE_NOTES
Inform users on the system of the release notes location.
If you have problems installing this ECO kit, please report the problem
to your local Digital support center or send Internet mail with details
(and a log of the installation attempt) to fortran@digital.com.
