Eliminated alternate font stuff.
changes to: FontForIndex: if a font cannot be made, $CDxCompatibilityFont is choosen, CDIO.MakeName is called to put wDir: "/Indigo/AltoFonts/" and ext: "Strike".
Edited on May 31, 1985 1:35:21 pm PDT, by Jacobi
redone completely for Cedar 6.0

changes to: ChangeFontComm: Change is applied to all selected instances.
