==Description==

AIPS runs under the [[X WindowsWindow System]] with commands entered interactively using a command-line interpreter called POPS. Although relatively primitive, this gives access to a useful collection of e.g. mathematical functions, logical operators and flow control statements. Commands can also be placed in a text file which makes repeating complicated procedures much more convenient and which can be used to create data-reduction [[Pipeline (computing)|pipelines]]. A more modern alternative is to install ParselTongue, a [[Python (programming language)|Python]]-based interface.

As well as the terminal window from which AIPS is started and commands entered, most AIPS sessions will by default contain two other windows, the AIPS TV and the Message Server. The TV is used to visualise data or images and can, for example, be used to interactively edit data or control the progress of a [[deconvolution]]. The Message Server displays useful information reported by each task. Optionally, basic black and white plots can be displayed using TEKSRV, a [[Tektronix 4010|Tektronix 4012]]-based graphics terminal.
