Yes, you can do this. 

A canonical exchange within the do file is 

di "Enter value for foo: " _request(foo) 

after which local foo contains the value typed. 

See -help display-. 

I'd rather take arguments from the command line, but that's a matter of
taste.

I have a do file, wherein I have a few scalars which I am using to
expand,
loop , as cutoff limits etc. Is it possible to have the do file 
prompt the user to input the value of the scalar, so that I do not have
to
make the changes to the do file.

Suppose I had a do file like

Scalar a=5
......
Expand a
.......

Can I get stata to prompt the user like 

Enter the value for expansion : 
that input then gets stored as a
The code executes..
