The development of this software tool started at CERN in 1986, it was optimized for the processing very large amounts of data. It was based on and intended for inter-operation with components of CERNLIB, an extensive collection of Fortran libraries. PAW had been a standard tool in high energy physics for decades, yet was essentially unmaintained.[1] Despite continuing popularity as of 2008, it has been losing ground to the C++-based ROOT package. Conversion tutorials exist.[2] In 2014, development and support were stopped.[3] Sample scriptPAW uses its own scripting language. Here is sample code (with its actual output), which can be used to plot data gathered in files. * read datavector/read X,Y input_file.dat* eps plotfort/file 55 gg_ggg_dsig_dphid_179181.epsmeta 55 -113opt linx | linear scaleopt logy | logarithmic scale* here goes plotset plci 1 | line colorset lwid 2 | line widthset dmod 1 | line type (solid, dotted, etc.)graph 32 X Y AL | 32 stands for input data lines in input file* plot title and commentsset txci 1atitle '[f] (deg)' 'd[s]/d[f]!
