[tex-k] Question about io.mf example

[Igor Liferenko]

Hi all,

I wonder if CTAN/systems/knuth/dist/lib/io.mf is meant
to correspond to io.mf on page 32 in MFbook.

io.mf on CTAN differs from MFbook's one on line 20:

    penpos1(stem,15); penpos2(stem,12); penpos3(stem,10);
    penpos1(stem,15); penpos2(.9stem,12); penpos3(stem,10);

Regards,
Igor
