In Phix, pipeio. e doesn't want to work relentlessly:

global integer address_length 
-- address length for pointers 
-- * 4 on 32-bit OSes 
-- * 8 on 64-bit OSes 
--</desc> 
--</variable> 
address_length = 4 
global procedure poke_pointer(atom addr, object x) 
--<procedure> 
--<name>poke_pointer</name> 
--<digest>put a 4 byte pointer in memory</digest> 
--<desc> 
--</desc> 
--<param> 
--<type>atom</type> 
--<name>addr</name> 
--<desc></desc> 
--</param> 
--<param> 
--<type>object</type> 
--<name>x</name> 
--<desc></desc> 
--</param> 
--<return> 
--</return> 
--<example> 
-- poke_pointer(addr, allocate_string("where?")) 
--</example> 
--<see_also>peek_pointer()</see_also> 
--</procedure> 
  if addr <= 0 then 
    printf(1,"poke_pointer: bad pointer %d\n", addr) 
  end if 
  poke4(addr, x) 
end procedure 
 
-------------------------------------------------------------------------------- 
 
global function peek_pointer(object addr) 
--<function> 
--<name>peek_pointer</name> 
--<digest>read a 4 byte pointer in memory</digest> 
--<desc> 
--</desc> 
--<param> 
--<type>object</type> 
--<name>addr</name>

--<return> 
--</return> 
--<example> 
-- addr2 = allocate_string("where?")

-- poke_pointer(addr, addr2) 
-- ? peek_pointer(addr) --> same as addr2 
--</example> 
--<see_also>poke_pointer()</see_also> 
--</function> 
  if atom(addr) and (addr <= 0) then 
    printf(1,"peek_pointer: bad pointer %d\n", addr) 
  end if 
  if sequence(addr) and (addr[1] <= 0) then 
    printf(1,"peek_pointer: bad pointer %d\n", addr[1]) 
  end if 
  return peek4u(addr) 
end function 
 
global function size_of( atom ctype ) 
  if ctype = #03000001 then 
    return address_length 
  elsif ctype = #03000002 then  -- T_LONGLONG 
    return 8 
  else 
    return and_bits( ctype, #FF ) 
  end if 
end function 

And for some reason, after the shutdown, a Phix error comes out, which I do not understand

f:\phix\pmsgs.e:337 in procedure Warnings() 
attempt to divide by 0 
    fn = 1 
    wi = {``,0,{`procedure error is not used.`,`F:\phix\out\pipeio.e`,311}} 
    buttons = {`Next`,`&Skip remainder`,0} 
    witxt = "Warning: F:\\phix\\out\\pipeio.e:311 procedure error is not used.\n" 
    fn1 = 1 
    r = <novalue> 
    i = 0 
... called from f:\phix\p.exw:2528 in function main() 
    savepath = `f:\phix\out` 
    outfile = <novalue> 
    CSvaddr4 = 2826282 
    ebp4 = 150825 
    esp4 = 114673 
    pst4 = 1058085 
    ntcb4 = <novalue> 
    wasEBP = 0 
    pi = <novalue> 
    dfn = <novalue> 
    i = <novalue> 
    i = <novalue> 
    paramstr = <novalue> 
    i = <novalue> 
... called from f:\phix\p.exw:2853 

The ex. err file is very large, I sent it to Pete
