batch adj. 1. Non-interactive. Hackers use this somewhat more loosely
   than the traditional technical definitions justify; in particular,
   switches on a normally interactive program that prepare it to receive
   non-interactive command input are often referred to as `batch mode'
   switches. A `batch file' is a series of instructions written to be
   handed to an interactive program running in batch mode. 2. Performance
   of dreary tasks all at one sitting. "I finally sat down in batch mode
   and wrote out checks for all those bills; I guess they'll turn the
   electricity back on next week..." 3. `batching up': Accumulation of a
   number of small tasks that can be lumped together for greater
   efficiency. "I'm batching up those letters to send sometime" "I'm
   batching up bottles to take to the recycling center."
