I have a routine that uses dynamic arrays. At certain
points in the program I need to clear out the arrays so
that they have NO elements (no UBound in other words),
just like in their virgin state.

For instance:

Option Base 1 'in declarations

Dim MyArray() As String 'a dynamic array with no UBound
ReDim MyArray(3) 'dimension for 3 elements
MyArray(1) = "Monday"
MyArray(2) = "Tuesday"
MyArray(3) = "Wednesday"

'now I want to return the array to the
'"no UBound" state like it started in.

ReDim MyArray 'compile error / syntax error
ReDim MyArray() 'compile error / syntax error
ReDim MyArray(1) 'no error, but UBound is now 1

Is there any way to do this?
