  10 // JPM  11/03/2017  Created this file
  11 // JPM  Sept./2018  Added a status bar and better status report, and set information values in a tab
  12 //
  13
  14 // STILL TO DO:
  15 // Feature to list the pointer(s) in the code using the allocation
  16 // To set the information display at the right
  17 // To support the array
  18 // To support the static variables
  19 // To add a filter
