Explanation
The error occurred during processing of a basic
telecommunications access method (BTAM) OPEN macro.  An OPEN routine
found that dynamic buffering was being initiated while the BTAM application
was running V=V.  BTAM dynamic buffering is not supported for V=V.

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
Add the ADDRSPC=REAL operand to the job
statement and initiate the BTAM application again (V=R).
