This sounds like a bad idea. The parameter can be saved 
as a scalar or a local macro, but using a variable for
the same number again and again is usually unnecessary. 

Still, there might be a good idea, or you might insist, so 
if so try 

gen rho = _b[/rho] 

but consider also

scalar rho = _b[/rho]
