Thankx for help
I have a couple of more questions
1) The Orignal Socket Created via socket & bind and later on used on the
listen is the one
which the server is listining on
Later on the socket reterived on the Accept via the Retcode is the one from
the Client
it is this socket used on Send And Recv
2) Can concurrent Sockets program receive input from a number of tcpip
clients with different tcp/ip address
thankx
in My Case its Windows program

Regarding EZASMI, I have used it quite extensively in two products that I am
involved in - the ECB list method seems to be the only way to correctly
manage the interface - there are just too many ways that EZASMI can get into
a "never post" style situation. It is a bit of a pain to have to keep
building and destroying timers around the call but worth it in the end.
GWA03PSA is the loaded address of EZASOH03 which is the EZASMI API module

Thankx
was that your IDEA setting ECBLIST (that way if TCP/IP doesn't post you
down get deadlocked)
re: GLOBAL storage there are 2 storage areas defined by it
GWAUSCNT
GWA03PSA
They dont seem to be refrenced by any of the EZASMI api's

A) The EZASMI global storage block contains important state information -
including things like the load epaddr of the API load module. You should
perform a USING on EZASMGWA for it.
B) If the INITAPI has been done correctly for the subtask, the logic for
ASYNC ECB API call should be something like :
(1) Clear TCPIP ECB
(2) Setup timer
(3) Build ECBLIST containing TCPIP EBC and timer ECB
(4) Call EZASMI API
(5) Wait on ECBLIST
(6a) If TCPIP ECB popped - cancel timer and then test TCPIP RC and ERRNO
(6b) If timer ECB popped - branch to "timeout" code

I am using async processing ECB=
a couple of more questions
A) Why would have to pass the address of the global stroage to the SubTasks
??
B) I debugging both Mother and Daughter task under TSO TEST ....
if retocde = 0 for the API's that 0 is a good return code for example
"takesocket" or "GetCleintId" should the ECB passed on WZASMI macro post in
my case it never does maybe because I have defined a INITAPI in the SubTask

(A) Yes - and if the subtask is going to TakeSocket pay attention to the
SUBTASK= keyword
(B) The way I have implemented this in the past is to have the mother task
pass a parameter list to the daughter subtasks that includes the address of
the EZASMI GLOBAL area - and then each subtask will obtain its own task
storage (TIE).
Another couple of points :
(1) If you are writing anything non-trivial, then I would advise using the
ASYNC ECB flavour of EZASMI.
(2) Before calling the send/recv interfaces, setup a timer and add its ECB
to an ECBLIST along with the ECB for the EZASMI call (and also your STC
"stop" ECB maybe) - this will help situations where communications are lost
midway thru a conversation and your EZASMI call hangs.

Does Anybody have any pointers re: concurrent TCP/IP Assembler programs
specfically
A)in the Subtak (attached program) do you have to issue a
INITAPI
B) It it necessary to use EZASM STORAGE=GLOBAL or STORAGE=TASK
when writting a concurrent (meaning using subtask to use the send and
receive) program
