Why? If RETCODE is negative there was an error on the call and there is
no socket returned.

Subject: bad sample code?

I was looking at the sample code(ezacicas) in sezainst listed
below for cics sockets programming. The takesocket is supposed to
return
the socket number in retcode+2 a halfword. If that's the case and
socket
number 1 was returned in retcode+2 wouldn't the error check after the
call be incorrect?

CALL EZASOKET,(SOCTSOCK,SOCKET_TO_TAKE,CLIENTID_LSTN,
X
ERRNO,RETCODE),VL,MF=(E,PARMLIST)
*
L R5,ERRNO Check for successful call
L R6,RETCODE Check for successful call
MVC MSGCMD,SOCTSOCK Set the API name
C R6,ZERO Is it less than zero
BL SOCERR Yes, go display error and terminate
STH R6,SRV_SOCKID Save the taken socket descriptor


Errno ds f
Retcode ds f
