The Physics Analysis Workstation (PAW) is an interactive, scriptable computer software tool for data analysis and graphical presentation in high energy physics (HEP). Developed at CERN since 1986, it is optimized for processing very large amounts of data. It is based on and intended for interoperation with components of CERNLIB, an extensive collection of Fortran libraries.
PAW has been a standard tool in the HEP field for decades, yet has essentially grown beyond maintainability. Despite continuing popularity, it has recently been losing ground to the C++-based ROOT package.
PAW uses its own scripting language. Here's a sample code (with its actual output), which can be used to plot data gathered in files.
