Actually, to be nit-picky, using ASCII 255 doesn't make ECHO output a
blank line...  Nor is that character an 'unprintable'...  it just
happens to be an INVISIBLE character -- like ASCII 0.  The unfortunate
thing about these invisible characters is that that sometimes I've run
into situations where they become visible, especially if you try to use
a terminal as the console.

One other annoying thing with the command processor is that there was no
means by which you can get the date and time w/o getting a prompt.  Of
course I've done things like make a file with only a newline (note you
CAN'T create one by doing echo.>newline since it contains a space before
the newline!) in a text editor and doing the following date<newline.
