Buffer pointer

The buffer pointer points to the area containing a record to be processed by the exit.

For OPEN Requests: This field contains the character string from the EXIT assembler option. If you did not specify a character string in the EXIT assembler option, this area contains spaces and the buffer length field is set to zero.

For READ Requests: This field points to an empty buffer area.

For PROCESS and WRITE Requests: This field points to the record supplied by the assembler.

All Other Requests: This field is set to zero.

Note:
The buffer pointer may not be the same for all calls to the exit, even if the exit is the same type for all calls.
