X'1034' DEST BLOCK NOT EXPECTED SMB

Explanation
The control block returned by FINDEST, representing the source name at
MSGODSTN, is not an SMB (either a local or remote transaction code block).

Programmer response
Locate the MSGODSTN name in the message, and verify that it is a valid
local or remote transaction code name. The control block address is in REG1
in the REG14-12 save area, and the block is at QTPDST.
