Function DevInquire tries to call return value

[ruilvo]

On line 627 return ret.value() should probably be return ret.value

(I'd make a pull request if I only knew how to use git decently)

To me it still seems to be a problem, even though it has remained like this for quite some time. I might make a pull request to solve it. Moreover, it seems that the return of this function DevInquire() should be of type c_long instead of c_double, according to my version of the ALP-4 documentations.
