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

Thankx
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.

Subject: Assembler TCP/IP
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
