096

Explanation
The error occurred during processing of a basic
telecommunications access method (BTAM) OPEN macro. An OPEN routine
found that dynamic buffer allocation had been specified in the DCBBFTEK
field of the data control block (DCB).  However, the OPEN routine
could not dynamically allocate buffers because the data control block
specified neither the address of a buffer pool control block (in the
DCBBUFCB field) nor the number and length of the buffers (in the DCBBUFNO
and DCBBUFL fields).

System programmer response
If the error recurs and the program
is not in error, look at the messages in the job log for more information.
Search problem reporting data bases for a fix for the problem. If
no fix exists, contact the IBM® Support
Center. Provide the JCL and the program listing for the job.

Programmer response
Correct the error by doing one of the following: Providing a buffer pool and specifying the address of its control
block in the DCBBUFCB field.
Specifying the number and length of the buffers in the DCBBUFNO
and DCBBUFL fields.
Handling buffering in the program and deleting the BFTEK=D operand
in the DCB macro or DCB parameter of the DD statement.

Then run the job step again.
