BATCH [, /QUIT]
Enter or quit batch mode. In batch mode, all input is read from the
current input stream (which may be either a file -- when executing a
@file command -- or the keyboard). In direct (= non-batch)
mode, commands are read from the current input stream, but requested
data is always read from the keyboard. If keyword /QUIT is
specified, then direct mode is selected. Otherwise, batch mode is
entered.
