ATB016I

Explanation
 Advanced Program-to-Program Communication (APPC)
is started with the indicated amount of buffer space available to
any one conversation. This message is issued to hardcopy only.
 You
can define the buffer space amount for a conversation on the CONVBUFF
subparameter of the PARM parameter of the EXEC statement in the APPC
member of SYS1.PROCLIB.  The CONVBUFF value is a 1- to 7-digit number
indicating, in kilobytes, the amount of buffer storage available to
one conversation.  If you specify a value between 1 and 39 on the CONVBUFF parameter,
the system uses a value of 40 (because 40 kilobytes is the minimum
buffer storage requirement per conversation).
If you specify a value that is not a multiple of four kilobytes
(decimal), the system rounds the value of CONVBUFF up to the next
highest multiple of four.  For example, if you specify CONVBUFF=1023,
the system makes 1024 kilobytes of buffer storage available to one
conversation.
If you a specify a value that is greater than the total amount
of buffer storage (which is specified on the BUFSTOR subparameter
of the START APPC command), the system issues message ATB017I to the
console, and allows a single conversation to have access to all of
the APPC buffers.

 The maximum possible value is CONVBUFF=2097152.  If you
do not specify a value for CONVBUFF, or if you specify a value of
zero, the system uses a default of 1000 kilobytes.
 In the message
