Hi all,

Is there any way to disable a once declared variable without
gROOT->Reset in interactive session? 
gROOT->Reset deletes all the variables and not always desirable.
Typical case is that a variable is declared with wrong type by mistake
as follows:
 
  *******************************************
  *                                         *
  *        W E L C O M E  to  R O O T       *
  *                                         *
  *   Version   3.04/02   11 January 2003   *
  *                                         *
  *  You are welcome to visit our Web site  *

  *                                         *
  *******************************************

FreeType Engine v1.x used to render TrueType fonts.
Compiled for linux with thread support.

CINT/ROOT C/C++ Interpreter version 5.15.68, Dec 12 2002
Type ? for help. Commands must be C++ statements.
Enclose multiple statements between { }.
root [0] int a
root [1] double a
Error: a already declared as different type FILE:/tmp/kkhYoc_cint LINE:1
*** Interpreter error recovered ***
root [2] 

     Best regards,
