Hi,
what is wrong with q[0], q[1], ..
And with
Table[q[n]=f[n],{n,0,40}]
or
(q[#]=f[#]) & /@ Range[0, 40]
?
Regards
Jens

I'd like to be able to define them all without writing out n assignment lines, so a Do loop seems appropriate to me but I don't know how to assign sequential variable names. This gets the job done but it is really ugly IMO
