AUTO-BUFFER* - This variable affects only non-networked, single-tasking machines (such as non-networked MS-DOS machines). When set to a non-zero value, this entry causes all disk I/O to be buffered (similar to MASS-UPDATE). In addition, to ensure that files are not easily corrupted by power failures, all disk buffers are flushed whenever one of these two conditions is met:
A Format 1 or Format 2 ACCEPT statement executes.
The count of file update operations (WRITE, REWRITE, DELETE) equals the value
specified for AUTO-BUFFER.
The default value is "50".
