• PAW (Physics Analysis Workstation) is an INTERACTIVE SYSTEM designed for data analysis and data presentation.
• PAW provides a set of COMMANDS acting on specific objects. The main objects or data type are: VECTORS, HISTOGRAMS, and NTUPLES. The aim of the tutorial is to illustrate with examples how to work with these objects in a data analysis process.
• The PAW commands are organized into a TREE structure.
• The general structure of the tree is:

                                                                                                                   
               OBJECT/ACTION                                                                                            

                                                                                                                   
               NTUPLE/PLOT                                                                                              
               HISTOGRAM/PROJECT                                                                                        
               VECTOR/DRAW                                                                                              

• The usual user interface is a ``command line interface'': commands are typed on keyboard and executed after . Commands parameters are separated with the blank character.
• Commands editing and retrieving is also possible. It is controlled via the command RECALL_STYLE (ksh, DCL etc ..).
• Commands can be grouped into ``Macros''. Macros are files with the extension .kumac containing several commands with eventually construction like ``do loop'', ``if endif'', etc .. . To execute a macro it is enough to type EXEC macroname if the macro is in the file macroname.kumac .
• It is possible to have online help on commands with the command HELP which gives the full description of a command, and with the command USAGE which gives the command syntax.
• A printable version of the reference manual can be obtain with the command MANUAL .
• PAW++ provides a Motif based User Interface to PAW.
• PAW and PAW++ have the SAME basic functionality.
