[AccessD] Treat string as array

A for next iterator.

Dim varChar as variant
For each varChar in arrSomeStr
	Do something with varChar
Next varChar 

Much cleaner than

Dim IntPtr
Dim varChar as variant
	for intPtr <=len(strSomeStr)
		varChar = mid(strsomestr,intprt,1)
		So something with VarChar
	next intprt

They both work but...

Strings are just pointers to an memory location on the heap.  Turning a
string into an array of characters SHOULD be a function call, optimized in
assembler to be blindingly fast.

What do you need that you don't get from MID?
