Getting Data from the Worksheet

In traditional programming (such as with C++), the source of input data is usually either the keyboard or (usually when there are lots of data) a file. When using VBA, which is an integral part of Excel, the natural source of input is from the Worksheet itself. 

The Cells method treats the spreadsheet as a two-dimensional array representing the rows and columns. If the variable ActRow is 3, for example, then the variable 

InputNumber is assigned whatever value is contained in the cell in the third row and first colnmn. It is possible using the Range object to write a statement that inpnts values from a collection of cells (but this tends to make things more complex than they need be).
