imp cf3db5046c Make sourcer's main program execute in X mode. 
o Make the dos emulation treat c: and C: the same way.  Sourcer was doing
  a chdir("c:\\") rather than a chdir("C:\\");
o use drlton() in all places where we used to use -'A' so that we're always
  case independent.
o use drntol() in all places where we used to use + 'A' for similar reasons
