Hi,

I'm trying to write a function similar to Save, but can't find how to
stop the main loop from evaluating the argument. Let's say I have the
definition

a=x^2

if I do 

Save[filename,a]

the definition goes into the file, what I want is to get the
definition into a variable inside my function, so I can do:

MyFunction[a]

and within MyFunction some variable gets assigned with a=x^2 (and not
just with x^2). Is there a way of doing this? I don't like having to
write MyFunction["a"]. In some way Save seems to know how to tell the
system not to replace 'a' with its value.

TIA
