The option to View Data within your Main File is available as a hyperlink at the top of matchIT’s main window, or within the View menu. It allows you to browse and update the selected Main File in any order. If you want to split the view into two partitions, move the mouse to the vertical black bar in the extreme bottom left corner of the view and you will see the cursor change to a double-headed arrow.
Click and drag it to the right and you will open up a second partition, which is very useful for comparing fields at the beginning of the record with those nearer the end. The Table menu allows you to unlink the two partitions, otherwise as you move up or down, the record position in each partition is kept the same.
