Hi Dimitris,

if you've got the old Limit.m somewhere on your disks, you can Get[] it:

In[1]:=
$VersionNumber
Out[1]=
5.1
In[2]:=
Limit[Nest[Sqrt[5 + #1] & , 5, n], n -> Infinity]
Nest::intnm: ....
Out[2]=
Limit[Nest[Sqrt[5 + #1] & , 5, n], n -> Infinity]
In[3]:=
Get["D:\\Programme\\Wolfram \
Research\\Mathematica\\4.0\\Addons\\StandardPackages\\Calculus\\Limit.m"]
In[4]:=
Limit[Nest[Sqrt[5 + #1] & , 5, n], n -> Infinity]
Out[4]=
(1/2)*(1 + Sqrt[21])
