4. mwkText is defined as Word.Application. It is use to open and close Word documents. wkFileName is set up to hold the name of the file. A default of mytext.doc is used if no name is entered into the text box. This calls fro a document which is blank and visible. The texture can be set a variety of ways. The index of 1 here is because this is the first document being edited. SaveAs saves the file name under the name entered or the default mytext.doc.

13. The form load makes the application visible and sets the cells on the top row with the column names. It then changes visible to false. Note that rowct is initialized at 2 to handle the headers and a blank row following the headers. Net is calculated and then the data is put in as the values of the cells using rowct to determine the number to determine the cell within that row. The application is quit and the object is set to nothing. PrPaySpx. vbp
