Subject: Re: Warnings


The Modula-3 compiler currently installed at SRC (a temporary version 
newer than release 1.2) complains about unused variables, which is 
good. However it also complains about unused formal parameters in 
procedures, which is not so good.  The problem is that often the 
programmer has no control over the parameters list, because he is 
often implementing a procedure whose signature is determined by an 
"immutable" interface.

I think a reasonable rule for selecting warning messages is that 
it must be possible for the programmer to fix the problem, and thereby 
eliminate the warning, without making the program significantly 
uglier/denser/longer/slower.

1.  A procedure declaration too long for one line leads to silly behavior.
2.  The final line lacks a newline character.

Here is an example exhibiting both these problems:

srcff 534> cat I.i3
INTERFACE SortedIntTable;
TYPE
  T   <: REFANY;
  Stream <: REFANY;
PROCEDURE NewStream (
     table: T;
     ascending: BOOLEAN := TRUE;
     key0 : Key := FIRST (INTEGER))
     : Stream RAISES {};
END SortedIntTable.
srcff 535> m3pp I.i3
INTERFACE SortedIntTable;
TYPE
  T      <: REFANY;
  Stream <: REFANY;
PROCEDURE NewStream (table    :
                              T
                     ;
                     ascending:
                              BOOLEAN
                     :=              TRUE           ;
                     key0     :
                              Key
                     :=              FIRST (INTEGER)): Stream RAISES {};

END SortedIntTable.srcff 536>

Does the Olivetti Modula-3 release run on a RISC computer?  We have a Solbourne
(don't know the model) and I can't even get a short program to run.

Subject: M3 on bsd4.3

I am interested in running Modula-3 under berkeley unix 4.3 (on a vax). 
I understand one can't get the Olivetti version at the moment, 
due to layoffs at ORC. Are you distributing the 4.3 version now, or
will someone do so soon ? Can you point me at someone who has the
Olivetti distribution ? Barring all that, how hard is it to port your 
system from Ultrix to bsd4.3 ? I need the source code, since I want to
make some experimental changes to the language, as part of my dissertation.

Many Thanks, Gilad

Subject: How can I get at the distribution ?

Help !

How do I get at the SRC files if I cant't ftp to 'gatekeeper.dec.com' ?
(BTW even if transfer over USEnet is technically possible it would be too 
expensive). So my options basically are BITNET or snail mail. My primary
interest at the moment is in the revised language report (I have got the 
original one).

Anyone got any ideas ?

Thanks^1000 !
