Msgbox "LBound: " & LBound(pets) & " Ubound: " & Ubound(pets) The following macro uses the LBound and Ubound statements to determine the size of the array variable. If the lower limit is 1 and the upper limit is 5, the array contains 5 values. Arrays always have a lower and upper limit, the Lbound statement returns the lower limit and the Ubound statement returns the upper limit. These functions are very useful. Array size - Finding the starting and ending index number of an arrayĮach element or value has a index number indicating its position in the array. The best analogy I can think of is if the first argument is the row number, the second argument is column number, the third argument is then like worksheets. It is also possible to have arrays with three dimensions. The italic numbers show the position of each value in the array. This picture is a visual presentation of the array variable. The first argument is the row number and the second is the column number, pets( row, column) Sub Macro1() This macro shows you how to populate a 2-dimensional array. There is a quicker way to transfer values from a worksheet to an array that I will tell you about later in this post. Pets(i) = Worksheets("Sheet1").Range("A" & i).value If you have many values this macro might do the work but this method is relatively slow. You can also grab values from a worksheet and save them to an array. The index number in the pets variable tells excel where to save the value in the array. In this macro 2 values can be stored pets(1 to 2). You can assign values to an array in your macro or user defined function. ![]() You are probably going to use one or two dimensions most of the time. The example arrays shown above have one dimension but it is possible to have up to 60000 dimensions. Note that this clears all previous saved array values. You can also change the amount of values an array variable can store any time in the macro, using the ReDim statement. This variable can store 5 values, 1 to 5. ![]() If you want to start with 1 instead of 0 you can do that too. The macro below declares variable pets as a string array, it can store 6 values. You can also specify how many values you want to store in the array. The parentheses shows that this is an array variable. The following line declares pets as a String array variable.
