Local procedure ReadWrite has 
Texts.Read(R, ch);
IF ~R.eot & (R.lib IS Fonts.Font) THEN
  Files.Write(Ri, c)
END

Consequently, after the final Read, which produces R.eot, the last 
character (c) isn't printed.  Ie. when decoding, the last character is 
always omitted.

ReadWrite is invoked only from inside WHILE ~R.eot ... .
Therefore ~R.eot should not be in ReadWrite.  This is better.

PROCEDURE ReadWrite(c: CHAR);
BEGIN
  Texts.Read(R, ch);
  IF R.lib IS Fonts.Font THEN
    Files.Write(Ri, c)
  END
END ReadWrite;

Comments?

Thanks,                             ... Lyall E.
