Basic Access Method z/OS DFSMS Using Data Sets SC23-6855-00 |

If you use a basic access method and want the system to assist in buffer control, you can control buffers directly by using the GETBUF macro to retrieve a buffer constructed. A buffer can then be returned to the pool by the FREEBUF macro. Because GETBUF does not support a buffer pool that is above the 16 MB line, IBM suggests that you write your own routine to allocate buffers above the line. |
