Naming Array Constants
Figure 14-4: Creating a named array constant.
Notice that in the New Name dialog box, the array is defined by using a leading equal sign (=).
Without this equal sign, the array is interpreted as a text string rather than an array. Also, you
must type the curly brackets when defining a named array constant; Excel does not enter them
for you.
After creating this named array, you can use it in a formula. Figure 14-5 shows a worksheet that
contains a single array formula entered into the range A1:G1. The formula is
{=DayNames}
Figure 14-5: Using a named array in an array formula.
Because commas separate the array elements, the array has a horizontal orientation. Use
semicolons to create a vertical array. Or, you can use Excel’s TRANSPOSE function to insert a horizontal
array into a vertical range of cells. (See the “Transposing an array” section later in this chapter.)
The following array formula, which is entered into a seven-cell vertical range, uses the
TRANSPOSE function:
{=TRANSPOSE(DayNames)}
You also can access individual elements from the array by using Excel’s INDEX function. The
following formula, for example, returns Wed , the fourth item in the DayNames array:
=INDEX(DayNames,4)
