Subject: Who I am ... and something new for MUI

    Hi everybody (and happy new year !),

    As I am new on this mailing list, I introduce myself.
    First of all, I am French and my English is very very bad as you can
see. So I apologize for this message and the ones which will come.
    Second, I am a student of a french ingeneering school (the ENSEEIHT) and
I am in the computer section of this school. Now, it's my third (and last)
year in this school. My favourite domain is computer architecture and assembling
language.
    Of course my personal computer is an Amiga (you know, the only one who
makes it possible...). My exact configuration is :
    - A2000B
    - a GVP 68030/68882 (40Mhz) board
    - 8 Mo FAST RAM
    - HD 100 Mo
    - kickfile 3.0
    My favourite interest with it is public domain, sometimes games and of
course system programmation. As it is difficult to program all in assembling
language, I choose the best (for my point of view) compilator for the Amiga,
namely Amiga E. I LOVE its speed and it is so easy to use.. but you know all
that.
    It's a long time I know this mailing list, but I never try to subscribe
it cause of my too bad English. But now I think I have good reasons to do it.
Indeed, I make a E preprocessor which only supports macros replacing. Why did
I make it ? Because I wanted to use MUI with Amiga E, and to program MUI without
macros is quite impossible. So with this preprocessor (called Mac2E), I made
all that is needed to use MUI 1.4 with. The good news is that a wonderful
MUI builder (written by a friend) will be available soon (see below). So
I convince my friend to make the generated code of his MUI-Builder to be
generic, in order to be able to generate any kind of code. And I success !
So MUI-Builder (for the moment) is able to generate C and ... E code. The very
good news is that I put Mac2E on aminet wednesday morning (in France), and my
friend will put his MUI-Builder (with my E code generation module) wednesday
morning too. Of course, if some of you want more precise information on them,
I can answer (e-mail me at [e-mail]). If there is a lot of identical
questions, I will make a global report to this list. I can also e-mail the 2
archives for those of you who haven't ftp access or who can't wait.

    That's all, I hope all these news will interest you...

    See you soon, Lionel

PS: Someone told me about a next 3.0 version of Amiga E which will be soon
available. Can someone confirm me this news (with perhaps a date...) ?

Does any one has or can build the Janus.m to use the Janus.Library, this
library let you control the Bridgeboards. If someone has a C example I can
convert it to E.

I had previously gotten SetFunction to work but I ran across the CreateProc
function on a different project. I wanted to try to "clone" Olaf Barthel's
little utility that opens a little window in the window title bar and
maintains a display of the current head number of each diskette on the
system and changes each time any diskette head changes position. This
program was called TrackDisplay by Mr. Barthel. I called mine E_TrackDisplay.
I had access to Olaf's C source code so I had a good head start on how to
write the program. Some of the items that I included in my code were:
cli/shell self-detaching, setting up an interrupt and tying it to the
verticle blank interrupt. In doing the cli self-detach, I effectively fired
up a copy of the E program via CreateProc (I'm running 1.3) and the trick
about copying the value of A4 was, of course, crutial to getting the
"cloned" program to run properly. If I recall properly, I saved a copy of
A4 so that the interrupt code could address E global variables. I passed
the value of A4 to the interrupt via the is.data field. In debugging the
program I had a situation where I was failing to free 24 bytes of memory
I used the SetFunction to trace AllocMem/FreeMem calls. That was a trip.
BTW, A4 provides the means to address global variables in an E program,
but if you are calling code and need to be able to address local variables,
you have to save and restore A5. As it turns out A5 will have a different
value if calling from the main procedure vs. calling from a PROC.

Subject: Address of field within OBJECT?


Hi!  I'm new to this mailing list so I don't know if this has been covered
before or not.  I'm trying to get the address of a specific field
within an object.  Is this possible?  Here's an example...

'exec/lists.m' has an object thus:

   OBJECT lh
     head     : LONG
     tail     : LONG
     tailpred : LONG
     <etc..>
   ENDOBJECT

In my source code:

DEF   broker_list : PTR TO lh;
      broker_list := New(SIZEOF lh);

Now, what I need to do is set 'broker_list.head' to the address of
'broker_list.tail'.  (This is part of the setup of a list header
for using exec linked list functions.  amiga.lib has routine NewList()
to do this but, alas, we don't have it in E... yet)

I tried this:

   broker_list.head := {broker_list.tail};

But E did not like it.  What I ended up doing was this:

   broker_list.head := broker_list + 4;

This is really poor style and I was hoping for a better way to it.
Any suggestions?  Thanks...

-Rob
