For those familiar with dynamic arrays, functions like Length (determine number of elements in the array) and SetLength (change the dimension of your array) are vital.
Strange enough, on rare occasion, using SetLength() might cause and "Invalid Pointer Operation" (EInvalidPointer) error or a "RunError(204)" ...
I've had that happen when making a populated array smaller (and not consistently I might add).
The fix was found in "clearing" the array with:
FillChar(MyArray,sizeof(MyArray), #0);
I thought it might be helpful to someone to find this little trick ...
