  84    This structure sort of takes the place of global variables or perhaps
  85 is the global variable.  (It can be accessed globally as ps_global.  One
  86 advantage to this is that as soon as you see a reference to the structure
  87 you know it is a global variable.
  88    In general it is treated as global by the lower level and utility
  89 routines, but it is not treated so by the main screen driving routines.
  90 Each of them receives it as an argument and then sets ps_global to the
  91 argument they received.  This is sort of with the thought that things
  92 might be coupled more loosely one day and that Pine might run where there
  93 is more than one window and more than one instance.  But we haven't kept
  94 up with this convention very well.
