ECO KIT SUMMARY:

An ECO kit exists for DEC Fortran 90 for Digital UNIX Alpha Systems Version 
2.0 on Digital UNIX Version 3.0 or later.  This kit addresses the following
problems: 


    -   For files opened for direct access, "fixed length records", the 
    	RTL would incorrectly output an error message if there was 
	a trailing X format statement that happened to output the 
        exact number of spaces remaining in the fixed length record

    -   During exit handler processing, if a unit was previously 
    	open and not closed before receiving a control-Y the FORTRAN 
	RTL would loop

    -   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")

    -   The DEC FORTRAN RTL would give a different IOSTAT value 
    	from the VAX FORTRAN RTL for VFE values which are out of 
	range

    -   The DEC FORTRAN RTL variable format expression (VFE) behavior 
    	no longer differs from the OpenVMS VAX behavior for where
	the VFE is evaluated during I/O list processing

    -   The FORTRAN RTL incorrectly recognized null repeat values for
    	list-directed I/O

    -   The FORTRAN RTL failed to re-enable interrupts, causing a 
    	running program to ignore control-C

    -   The FORTRAN RTL failed to completely initialize some 
    	extended formatted records with blanks

    -   The FORTRAN RTL incorrectly produced an input conversion error
    	(INPCONERR) for some small integer conversions

    -   The FORTRAN RTL SECNDS function failed to account for 
    	daylights saving time

  o  The following changes to the DEC Fortran documentation should be noted:

    -   The rules for G format switching between E and F formats have been
    	refined as part of the Fortran 90 standardization process.  The new
    	rules say if 0 < N <= 0.1 - 0.5 x 10**(-d-1) or N >= 10**d - 0.5,
    	then treat as kPEw.d.  For N = 0.0996 and -1PG11.3, the RTL now
    	sees that 0.0996 <= 0.09995 so it uses kPEw.d, resulting in
    	formatted text of 0.010E+01.  The RTL used to use kPFw.d and 
    	get 0.100 .


INSTALLATION NOTES:

    1.	Create a directory to hold the product:

		mkdir /usr/local/dfartl
		cd /usr/local/dfartl

    2.	Copy the product from the distribution device or area
        to the temporary product directory you created in step 1.

		cp [location of distribution file]F90RTLAUE01020.tar .

    3.	Uncompress and unpack the product.

		tar xmpf F90RTLAUE01020.tar

        This creates the subset DFARTL365 files in the local directory
		
    4.	Run setld to do the installation.

	    -	Install the subset with:

			setld -l /usr/local/dfartl DFARTL365

	        and follow displayed instructions.

	    -	Installation verification must be run separately:

			setld -v DFARTL365

    5.  Remove the temporary directory and its contents:

		rm -r /usr/local/dfartl

UNIX Alpha Systems
