Recent discussions of word and letter spacing in Word 4.0 suggest that the
PostScript generated by Word might be worth seeing.  Here is an example.


The PostScript command "awidthshow" prints a character string while adjusting 
the spacing between words and between letters.  The command takes six 
parameters:  cx, cy, char, ax, ay, and string.  The string parameter is the
string to be printed.  The parameters cx and cy are added to the x width and
y width, respectively, of all occurrences of the character char within the
string.  This feature is generally used by specifying the space character as
char and the extra spacing between words as parameter cx.  The parameters ax
and ay are added to the x width and the y width of all characters.  If
parameter ax is greater than zero, extra space is inserted between letters
in words.  Here is what this paragraph looks like when formatted by Word 4.0
in 12 point New Century Schoolbook with a 6.5 inch justified line.

Notice that parameter ax is greater than zero and different for each line.
Hence each line has different spacing between letters of words.
