I know that the string, "/sys/class/..." is an ImmediateBox, which is leveraged in an InvokeExprBox (specialinvoke $r1...). What I cannot seem to manage to figure out is how to derive the Local $r1 variable from either the InvokeExprBox or the ImmediateBox. Neither of them have any formal link to $r1 (a Local) other than by parsing the string representation of them and then going through the Locals looking for what you want.</div><div><br></div><div>So my question is: Is there a way to get the Local from the InvokeExprBox or the ImmediateBox in this case, or the general case?
