The fields on the right-hand side in the “Event” view are used to specify which cell the event should be linked to. These fields are only relevant for the event types “Set data” and “Get data”. In the “Workbook” field you enter the name of the workbook where the spreadsheet of interest is stored. This workbook should always be open when you run a simulation. If you leave this field blank, MS Excel 5 will assume that the spreadsheet is located in the workbook you opened first in the current MS Excel 5 session. Thus, unless you always open just one MS Excel 5 workbook at the time, you should enter a workbook name in the “Workbook” field. In the “Sheet” field you enter the name of the sheet containing the spreadsheet of interest. If you leave this field blank, MS Excel 5 will assume that your spreadsheet is in the first sheet of the workbook. In the “Cell” field you can enter the cell address in the following form: R1C1 If you have used the “Define name…” command in MS Excel 5 to give a name to the cell you want to link to, you have a second option: Enter the cell's name into the “Cell” field. This is option is very convenient if you later add rows or columns to your spreadsheet, and hence change the absolute address of some of the cells.
