but it is not invoking the Sn0400
can any one help me

Code:
SN0200: PROC($LTM,$PCB1) OPTIONS (MAIN NOEXECOPS);

i am using the following psb's

PCB TYPE=TP,MODIFY=YES
PSBGEN LANG=PLI,PSBNAME=SN0200,CMPAT=YES
END

PCB TYPE=TP,MODIFY=YES
PSBGEN LANG=PLI,PSBNAME=SN0400,CMPAT=YES
END

What do the put skips in sn020 say? Any reaction from the system like an abend or status-code (you'll have to declare and base the iopcb-structure over the $LTM pointer in sn0400 to find out)? Message class for sn040 defined in any region? Does the sn040 exist (did you try /DIS TRAN SN040 & /DIS PROG SN0400)?

0462, like I posted before, is because in an MPP there are successfull DLI-calls but these call have not been preceeded by a GU on the message queue. First in sn0200 call:

Code:

CALL PLITDLI (N3, 'GU', IOPCB, IOAREA);

From the documentation it definitely states:
Quote:
Code 0462

0462
Explanation:
An application program was scheduled in a message region and terminated without successfully issuing a GET UNIQUE for an input message. The application program did successfully process at least one other call.

System action:
The application program is abnormally terminated, and the PSB and the SMB are stopped.

Programmer response:
Determine the problem in the user message processing program, correct it, and resubmit the job.

You may try to code a second call following the GU for the first message; this would be a GN at the IO-PCB; when status-code = 'QC' all messages for your SN0200 have been read. Also your SN0400 has to start the first DLI-call with a GU of the message SN0200 has send.
