Question: Problems with Compiling Procedures

I'm having problems using Compiler:-Compile() on the following procedure: findallroots:=proc(eqs,x,rng::range(numeric)) local roots,pts,i; roots:={fsolve}(eqs,x,rng,'avoid'={x=lhs(rng),x=rhs(rng)}); if roots={} or not roots::set(numeric) then NULL else pts:=sort([op(rng),op(roots)]); op(roots),seq(procname(eqs,x,pts[i-1]..pts[i]),i=2..nops(pts)) end if; Error, (in IssueError) only named functions are supported If you could help me with what this error is referring to and what I could do to over come it that would be most appreciated. Thank you for your help
