Differencing Two Data Files

You will presented with a standard Windows file box dialog twice.
- The 1st dialog is to open the 1st file.
- The 2nd dialog is to open the 2nd file.
Two data sets are then input into the program
- the 1st file data (you might for instance like to compare the difference
between the files with the original data).
- the 1st file - 2nd file. It is assumed that both files are the same
size (i.e. the x and y dimensions are the same and the same number of data
sets are included). If the files have a different number of data sets Viewer
does its best to match up corresponding data sets and then only reads in
those that match. NOTE: In the drawing menus this latter data set has (-)
before it in the menu to remind you it is the previous data set in the
menu minus that data set.
