PAIRS v1.2 by David GJ Cole (c)1998

-OVERVIEW-

PAIRS is a Personal Productivity application for the Psion 3a/ 3c/ 3mx that 
applies the "Pairwise Comparison" technique to a set of options to both 
prioritize these options and determine the relative importance of each option to 
the others. 

Situations often arise where a number of activities must be completed, but it is 
not immediately clear which must be done first (e.g. Time Management and ToDo 
list prioritisation). Alternatively, a decision may have to be made on the basis 
of a number of considerations whose relative importance is not known (e.g. 
deciding whether to move to location A or B). PAIRS is designed to help with 
both these types of problem. 

Example uses of PAIRS can be found at the DGC Shareware website URL 
http://www.dcole.freeserve.co.uk

Any comments, suggestions (or bug reports!) would be appreciated. Please send 
them to DGCShareware@dcole.freeserve.co.uk

 
-INSTALLATION-

The download package was zipped with the appropriate directory structure for the 
Psion, and files should be copied to the Psion to reflect this structure. This 
can be done by using the command line PKUNZIP -d PAIRS12.ZIP. If the directory 
structure has not been re-created or you have not created Psion directories 
before, please use the following: 

    If it does not already exist, create a directory \App on the Psion internal 
    drive by using the sequence: "Menu -> Disk -> Make directory -> \App". Copy 
    the PAIRS main program PAIRS12.OPA to this directory. Alternatively, this 
    file can be copied to, and run from, a \APP directory on either SSD A or B. 

    Create a directory \Pairs on the Psion Internal drive by using the sequence: 
    "Menu -> Disk -> Make directory -> \App\Pairs". Copy the Pairs helpfile 
    (PAIRS12.HLP) to this directory. (see note below). 

    Install PAIRS and its icon by using Psion-I from the Psion 3a/ 3c/ 3mx 
    system screen. The icon will be installed to the left of the current cursor 
    position. 

    When PAIRS first runs, it will create a directory \Pairs on the Psion 
    Internal drive. This will be used to store all data files generated by 
    PAIRS. 

In addition, the following files are included with the PAIRS v1.2 download 
package: They should not be downloaded to the Psion. 

    README.HTM - This file, giving installation and Help information. 
    README.TXT - a plain text version of this file. 


-A Note on the PAIRS HELP FILE-

Installaton of the help file is recommended, but if memory space is at a premium 
you can either download it and delete it when you are familiar with the software 
or not download it at all. To get you started, the PAIRS Menu Helpfile entries 
are included below: 

    Help: File menu
        New: clear the current options and create a new file. TAB can be used as 
        a 'Hot Key'. 
        Open: open a previously saved PAIRS file. 
        Save: save the current options to the current PAIRS file. 
        Save as: save the current options to a different PAIRS file, or as text 
        for other applications. 

    Help: Options menu 
        Insert: insert a new option. Press Esc/ Enter to finish. 
        Edit: use the arrow keys to select the option to edit. Press Enter to 
        start the edit this option. 
        Delete: use the arrow keys key to select the option to delete. Press 
        Enter to Delete this option. The Delete key can also be used as a 'Hot 
        Key'." 

    Help: Priority menu
        Prioritise - prioritise the current set of options by asking the user to 
        compare successive pairs of options. 
        Display - redisplay the current set of options in priority order. 

    Help: Special menu
        Zoom in - increase the font size. 
        Zoom out - decrease the font size. 
        Print setup - set up the printer for the current options. 
        Print preview - preview the current print setup. 
        Print - print the current set of options. 
        Exit, lose changes - exit PAIRS without saving changes. 
        Exit - exit PAIRS after saving any changes 

    Help: Tips on using Pairs
        Although PAIRS supports up to 15 options, it is best to limit the number 
        of options as this reduces the number of questions PAIRS asks. If you 
        have more than 15 options, a good approach is to allocate them to 
        categories, prioritise the categories before prioritising the contents 
        of each category. The weights for the categories and the individual 
        options can then be used to combine all the options to get an overall 
        prioritisation.
