****************   Notes for Windows AX   ***************

The program is simple and should be relatively obvious
even for the new user. The main steps involved are:

1) Create an input file; this may be done either with
  your favourite editor, or from within AX itself.
  The data file consists of a line of 11 oxides (these
  and ONLY these 11 are accepted currently by AX, although
  they can be placed in any order on the first line of the
  data file - see the example below). Save it with a .txt
  extension.
  
  Each analysis is entered as a pair of lines, the first
  of which gives the mineral code (g, cpx etc) and a brief
  title. (A list of the mineral codes can be found from the
  help menu in the program). The second line gives the oxide
  wt% values in the SAME order as the oxide names in the
  list at the top of the file. 
  Data may be tab-, comma-, or space- delimited, and the
  file is termnated with an asterisk.
  
  An example follows:
  
  SiO2 TiO2 Al2O3 Cr2O3 Fe2O3 FeO MnO MgO CaO Na2O K2O
  g gt
  39.70 0.00 23.20 0.00 0.00 23.60 0.50 7.60 7.00 0.00 0.00
  cpx omph
  57.20 0.00 12.50 0.00 0.00 4.70 0.00 7.00 10.20 8.00 0.00

2) Run the program. Double click the AX icon, and the opening
  window panel is displayed, which allows you four options.
  These are
  
  RUN: opens a fileOpen dialog to select an existing datafile
       which is then run. The resulting output file is then
       displayed in an editable window. In addition to this
       output (*.out extension), the program generates two
       additional files: 1) a tab-delimited output of the
       mineral data in a standard column form (*.tab) and
       2) an input file for use in THERMOCALC, which should
       be edited (and probably pruned severely!) before use.
       
  FILE/EDIT: this button takes you to the editor, opens up
       a tiny sample datafile which may be used as a template
       for creating and saving your own new datafile.
       
  EXIT: this closes down the application. The application
       may also be terminated by double-clicking the box at
       the top-left of the main panel window.
       
  LIST MINERAL ABBREVIATIONS: this button throws up a dialog
       box showing a list of the mineral abbreviations.
       
  The editor allows only basic functionality such as cut/paste,
  find/replace, save/saveas etc.

3)  3 kinds of output file are generated:

    1.  *_o.txt     the main recalculation output.
    
    2.  *_tab.txt   a tab-delimited file of mineral analysis
                    tables, paged for A4 output.
            
    3.  tcd**.txt   a file suitable for editing and submission
                    to THERMOCALC as input.     
                    N.B. Eliminate all doubtful endmember data (either
                    because of disequilibrium character - e.g. retrograde
                    phases, or because the end-member is the dilute
                    endmember on a solvus limb - e.g. paragonite endmember
                    in a potassic white mica whose activity will be subject
                    to prohibitively large uncertainty.
