If you have done any programming in VBA, you know the value of using variable arrays to store information. It is not uncommon to start working with large arrays in your macros. For instance, you might declare a 100-element string array, as follows:
Dim MyText(99) As String
As your macro executes, information can be stored and restored in the elements of the array. At some point, you may want to erase all the information in the array. One classic way of doing this is using a For ... Next loop to step through each array element, as follows:
For J = 0 To 99 MyText(J) = "" Next J
When the looping is complete, everything has been erased from the array. A quicker way of accomplishing the same task is to use the Erase function, as follows:
Erase MyText
Once executed, this single line sets each element of the MyText array back to an empty string. If the array is numeric, then each element of the array is set to zero.
There is one caveat with using the Erase function: If the array being erased were originally dimensioned at run time using the ReDim statement, then Erase gets rid of the dimensions and you'll need to use ReDim again to set them.
