Thanks, I thought I tried that... I'll give it a go.

The simple answer is, use 'mpfitFUN' if you are using a fitting function.
Then you could do this,
function myfunct, x, p, other=other
;; calculate y using x, p, and other
return, y
end
and
pout = mpfitfun('myfunct', x,data,err,p,parinfo=parinfo, functargs={other:other}
