I am just 'playing around' with METAFONT, and am having trouble getting
a look at what I've produced. I am using emTeX's METAFONT Ver. 1.7 [2g]
and have no trouble gettting io.dvi file and io.120. These seem fine,
as gftype io generates a file that 'makes sense' and
gftodvi io.120/ grayfont grayfx  responds by saying that it has generated
17 pages (this is the io excersize in the METAFONT Book on pgs 35 - 40).

The problem is that I know I need to turn the font into a 'local' thing,
but what I try to run gftopxl io.120 I get the following:
This is GFtoPXL, Version 2.1 [1d]
 Bad GF file: ID byte is 0!
run-time error R6001
- null pointer assingment

(Yet, no problem with this file with the other GFto... files)
Anyone know what my problem is? Will I really have to down load a newer
version? (The last link is at 2400 baud...I'd like to avoid that).

Thanks.
