* Excel 7 for Windows '95
  
  GraphMaT has been tested with Excel 7 for Windows 95.  The macros run as in 
  Excel 5 for Windows 3.1.  However the XY graphs created using Lotus 
  keystrokes or macros are displayed incorrectly due to a problem in Excel 7. 
  The graphs have what appears to be a line type graph axis and no data points 
  appear on the graph.  
  
  If you have Excel 7 and want to try GraphMaT, you can run the macro.  After 
  it is finished, save the file.  Then close the file and reopen it.  Select 
  the graph and choose Format Autoformat.  Then select XY(scatter) and select 
  one of the scatter graph formats displayed.  The autoformat will redefine 
  the axis correctly and display the points. 
  
  Since GraphMaT does display the graphs correctly in Excel 8 for Office '97, 
  it is therefore recommended that GraphMaT not be used with Excel 7 and that 
  you upgrade prior to testing GraphMaT.

* Microsoft Office 97 (Excel 8 for Windows '95 or Windows NT)
  
  GraphMaT has also been tested with version 8 of Excel which is a part of 
  Microsoft Office 97.  The problem noted with version 7 has been corrected, 
  however two problems which affect GraphMaT were encountered.  Both have been 
  addressed in version 2.21 of GraphMaT. 
  
  The first problem is that user menus which contain a formula were improperly 
  displayed.  These menus were replaced in version 2.21 of GraphMaT. 

  The second problem is that when combining named ranges, Excel 8 only brings 
  in cells from column A.  This is a more serious problem for GraphMaT since 
  it uses this operation to bring the macro code into 0GRAPH.WK1 from the 
  GRAPH.MAT file and to bring in data in some tutorials.  This problem can be 
  circumvented by using the cell addresses instead of the range name.


  1. To start a new macro using 0GRAPH.WK1 select the User graph and enter the 
     cell address for the desired macro when prompted for the name of the 
     macro.  The addresses from the macros in GraphMaT version 2.21 are given 
     the table below.  For example, to start the macro to solve simultaneous 
     equations in Tutorial 1 (page 27), type 

                [Alt+G] New User A391.T422 [Enter] 

     This is the equivalent of making the following selection from the menus. 
     
                [Alt+G] New Function Simultaneous 

     
                                Macro   Address
                                -----   -------
                                REG     A51.U88
                                LLD     A91.U128
                                MULT    A131.T151
                                NORD    A161.T189
                                CFIT    A191.W218
                                XREG    A221.U297
                                YFX     A311.U350
                                GX      A351.U390
                                SIMUL   A391.T422
                                EQN     A451.T491
                                PLOT    A501.X556
                                TRAN    A561.T669

     These addresses have been programed into 0GRAPHXL.WK1 so that the macros 
     can be started as shown in the GraphMaT User's Guide.  However, if a file 
     created from this file is used with a different version of GRAPH.MAT it 
     may not work properly.

  2. When using the Combine options during a macro or when using the GraphMaT 
     utility macro, specify cell addresses instead of the range name if the 
     data is not all in column A.  Starting with rev 2.21 of GraphMaT, 
     wherever possible the sample files are arranged so column A contains all 
     the data.  In two cases data points for several variables are combined 
     simultaneously.  For these use the cell addresses given below instead of 
     the range name. 

        Page    Range name      Cell addresses    File name
        ----    ----------      --------------    ------------
         37     DATA            B2.J28            NBASTATS.WK1
         54     IND             B193.F212         SAMPLES.WK1
