I doubt this is what's wanted.  If you want a new `math version',
which uses non-math italic *for letters only* rather than having to
use \itmath all the time, then in the current NFSS (I think) you have
to use the low-level commands.  itma.sty looks as though it was lifted
from Spivey's zed.sty.  I have patches to this to use NFSS, but
Sebastian Rahtz has done similar things -- check out oz.sty in his
PSNFSS distribution in the archives.

[This is a common thing to want to do in computer science, setting
equations with variable names rather than single-letter symbols.  It's
better supported in the test NFSS2 implementation -- not yet
released.]
