  10 // JPM  08/31/2018  Created this file
  11 // JPM  09/12/2018  Added a status bar and better status report
  12 // JPM  10/20/2018  Added the return address information in the call stack
  13 // JPM  08/09/2019  Prevent crash in case of call stack is out of range
  14
  15 // STILL TO DO:
  16 // To set the information display at the right
  17 // To use DWARF frame information?
  18 // To check if call stack pointer is used (DWARF information?)
