Ok, after a long week-end spend in the IDL6 "stupid PDF" help, I give
myself an answer.

function myfunc,x
common myfunca,a
return,f(x,a)
end

function solvef,b
common myfunca,a
a=b
x=fx_root([0,1,2],'myfunc')
return,x
end

I was missing the common block trick.
Thanks for your answers and procedures,
but they are way too complicated for me.
