<DIV>Hi Fredrik!</DIV>
<DIV> </DIV>
<DIV> First of all thanx for such quick answer! Please note
that I don't want to use erlang environment to run my programmes. I want to
compile them and move to another Linux machine. That is why I'm using "aLike
2.0" compiler. Both programmes can be compiled without any problem. Than I
start ./echo and ./client. The client can send only Integers. But when the
client tries to send a message that is: echosrv ! {ClientPid, N} error occurs:
<BR>{badarg,[{client,main,1}]}. So I comment this line (%%%) and as it is
expected every thing works correctly. It means the client tries to receive
message (see attach) which is the next thing it does. That is why I assume that
echosrv ! {ClientPid, N} is wrong order. I wrote before about little differences
between progs. run on erlang environment and progs. intended to be compiled and
run on Linux.</DIV>

erlang processes on differnet erlang nodes, which can be located on different
hosts. So, I guess that's a yes to your question. However, in order
to do so must all involved erlang nodes have the same cookie (at the time of
the message sending) and must also have networking turned on (see doc for erl:

kind of error are you having with "Srv ! {self(), Msg}" ? This statement adds
the erlang term "{self(), Msg}" to the mailbox of the Srv process, which can
be read by having the Srv process execute a receive-statement (which reads one
message from the mailbox).</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2>Halo!</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2> Despite the fact I'm working
for Panasonic Poland, I'm also a student of Warsaw University of Computer
Science Dept. I'm now to write a program using functional language. I have
chosen Erlang and decided to write an echo server. Yet, I would like to
compile that to executable files either server and client. I'm using Linux
Mandreak 8.1 and eLite 2.0 that contains a compiler. The problem is that the
error occurs when I'm trying to do "Srv ! {self(), Msg}". I mean it compiles
but doesn’t work! I have already got know that there is difference when I'm
writing for eLite. For example I must do erlang:halt(). insted of halt().
What should I do? <BR> Also, dose "Srv ! {self(), Msg}"
messaging work as pipe in Linux? Can I communicate to another process from
other terminal on the same machine?</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2> I'm waiting for any help!
Thanx!!!!!</FONT></DIV>
