This variable causes the system's buffers to be flushed whenever a Format 1 or Format 2 ACCEPT statement is executed. You turn on this variable by setting its value to "1" (on, true, yes). The default setting is "0" (off, false, no). This variable is particularly useful for MS-DOS sites that have a habit of turning off their machines. Note that this variable is not recommended for multi-user systems because of the performance penalty.
