g77

The following statement works on a number of platforms
but it generates the following diagnostic:
 
         OPEN (IUS,FILE='/tmp/invsrtf.scratch',STATUS='SCRATCH',
                   1                           2
Conflicting I/O control specifications at (1) and (2)
make: *** [invsrtf.o] Error 1

I can build a work-around but I am interested to know if there is a patch
or if it is considered a design feature.  Moreover, using 'info g77' I never
found a description of all 'OPEN' keywords.  A search for all occurances of
the string 'OPEN' revealed: (1) suggestion that "FILE='...'" is not necessary 
if one uses "STATUS='SCRATCH'"; (2) a disclaimer that OPEN is incomplete;
(3) suggestions that some warnings have been changed to errors.  However, there
was no definitive table (which I have seen in Cray, Sun and IBM documentation); 
hence the second question: Is there something missing from this installation's 
'info g77'? 

I expect to discover you are now working on much newer versions (and
are unconcerned about this old code)!  Is there a "history" web page to
dig up a chronology of patches?

Thanks in advance for your time.
