# Batch Processing in SICS

Users rarely wish to stay close to the instrument all the time but appreciate if the control computer runs the experiment for them while they sleep. SICS supports two different ways of doing this:

- SICS has a built in macro programming facility based on the popular scripting language Tcl. The most primitive usage of this facility is processing batch files.
- Second there is the LNS Rünbuffer system.
- Third there is the new Batch File execution system.
