   Hi, Chris

   You have written that

>> The present version of f2c allows Hex Constants like z'ff' in data
>> statements as well Z format in Format statements.

>> Look at this piece of f2c fortran:
>>         program hex
>>         data i/z'ffff'/
>>         i=i-1
>>         write(*,'(Z8)')i
>>         end
>> 
>> Compiled and linked using f2c and gcc form 1.08 works fine for me.

   Your quiet right mentioning compiling and linking, but I mean GO step.

   See yourself:

>f2c test.f
   test.f:
      MAIN hex;                   

>gcc test.c -lf77 -li77 -lm -lc   
>go32 a.out

   d:/dj/bin/go32.exe version 1.08 Copyright (C) 1991 DJ Delorie
   startio: error in format
   apparent state: unit 6 (unnamed)
   last format: (Z8)
   lately writing sequential formatted external IO
   Abort!

   This means there is bug in libi77.a, and if you look in its sources
you will see there is just bug, i.e. there is actually no run-time code 
for Z format at all, by the way releasing of the O format has bug too.

   We have done right code and could send for anybody, but what can we do
to include this in next release of f2c?

   With my kind regards
   Valery
