Enumeration can assign default numerical values or specific values can be assigned. End Select Boolean operators are simply TRUE or FALSE switches that process really quickly.Public Enum enum Gender Male = 0 Female = 1 Unisex = 2End Enum Dim Gender as enum Gender Select Case Gender Case Male (insert code here)... In the example below b Male, b Female and b Unisex are Boolean variables.The second command only recalculates a specific sheet.The third command only recalculates a specific Range.If you need to recalculate spreadsheet values while the macro is running you can use any of the following commands.The first command recalculates the entire workbook.I had naively assumed that common worksheet functions would be efficiently processed by VBA. For example, most VBA users are probably aware that VBA does not have a Max() or Min() function. It is common to use the following code that uses the Excel version of Max(): I found an open source version of a VBA Max() function on the Internet.It was 10 times faster than the Excel based counterpart above. I concede that the function below only works with two arguments and does not support arrays, but the improvement in speed is substantial.

I can't say that all "Application." functions are slow.

It is much faster to read the data once and save it into memory than to reread it each time.

In this example, the macro will need to grab the named Range "issue_age" from the worksheet repeatedly. VBA is much faster when it doesn't need to stop and interact with the worksheet.

The first five rules generally have the largest impact on macro performance. Please note that my estimates of time savings below may vary significantly for your specific application. When a new value is entered into a worksheet cell, Excel will recalculate all the cells that refer to it.

If the macro is writing values into the worksheet, VBA will need to wait until the worksheet is done recalculating each entry before it can resume.
