This was one SAS program running on one SAS session running on my desktop.  It is the \
server listening for the client.

4    filename local socket ':5000' server reconn=3;
5       /*The server is using a reserved */
6       /*port number of 5000.           */
7
8    data tcpip;
9       infile local eov=v;
10      input x $10;
11      if v=1 then
12         do;              /* new connection when v=1 */
13            put 'new connection received';
14         end;
15      output;
16   run;

NOTE: TCP/IP XX Access Method Listen portno is 5000.
NOTE: The infile LOCAL is:
      Local Host Name=XXXX,
      Local Host IP addr=XXXX,
      Listen Portno=5000,Client Hostname,
      Client IP addr,Lrecl=256,Recfm=Variable

NOTE: TCP/IP XX Access Method has connected to client at IP addr XXXX .
NOTE: The infile LOCAL is:
      Local Host Name=XXXX,
      Local Host IP addr=XXXX,
      Listen Portno=5000,
      Client Hostname=XXXX,
      Client IP addr=XXXXLrecl=256,
      Recfm=Variable

NOTE: TCP/IP XX Access Method has connected to client at IP addr XXXX .
new connection received
new connection received
new connection received
new connection received
new connection received
NOTE: The infile LOCAL is:
      Local Host Name=XXXX,
      Local Host IP addr=XXXX,
      Listen Portno=5000,
      Client Hostname=XXXX,
      Client IP addr=XXXX,Lrecl=256,
      Recfm=Variable


This was the client.

1    filename remote socket 'XXXX:5000';
2
3    data _null_;
4       file remote;
5       do i=1 to 10;
6          put i;
7       end;
8    run;

NOTE: The file REMOTE is:
      Local Host Name=XXXX,
      Local Host IP addr=XXXX,
      Peer Hostname Name=N/A,
      Peer IP addr=XXXX,Peer Name=N/A,
      Peer Portno=5000,Lrecl=256,Recfm=Variable

NOTE: 10 records were written to the file REMOTE.
      The minimum record length was 1.
      The maximum record length was 2.
NOTE: DATA statement used (Total process time):
      real time           0.04 seconds
      cpu time            0.01 seconds


I submitted the client program several times.  I am curious to why "new connection \
received" was not printed to the log ten times?

Thanks,

Kevin
