missing FONTDIMEN

During some past discussions on this list, quite a lot of people have
claimed similar things. I would therefore conclude that at least this
assumption of yours is wrong. :-)

The PL files \transformfont generates (by calling \mtxtopl) are not meant
to be used for anything else than being base fonts for virtual fonts,
therefore they do not need any fontdimens. If you want a font with
fontdimens, then you should generally do something like:

   \transformfont{eurmo10}{\slantfont{167}{\frompl{eurm10}}}
   \installfonts
      \installrawfont{eurmo10}{eurmo10} <six more parameters>
   \endinstallfonts

You will also need a suitable ETX file, since it is ETX files which set the
fontdimens. I noticed (while searching my hard drive for eurm10) that the
mathinst package contains a file named eurm.etx; that might be what you
need.

I can't help you here, I'm afraid. I have never bothered to examine how
checksums are computed.

PS: Why do you want to make an eurmo10 in the first case? The impression I
got (from looking at the metafont source) is that eurm10 is a math italic.
