Try with the following:


Mathematica 3.0 for Linux
Copyright 1988-97 Wolfram Research, Inc.
 -- Motif graphics initialized -- 


In[2]:= ?CleanSlate
   CleanSlate[] purges all symbols and
   their values in all contexts that have
   been added to the context search path ($ContextPath), since the
   package was read in. This includes user-defined symbols (in the Global`
   context) as well as any packages that may have been read in.
   It also
   removes most, but possibly not all, of the additional rules for System
   symbols that these packages may have defined. It also clears the In[] 
   Out[] values, and resets the $Line number, so new input begins as 
   In[1].CleanSlate["Context1`","Context2`"] purges only the listed

In[3]:= a=1

Out[3]= 1

In[4]:= Print[a]

In[5]:= CleanSlate[]
contexts purged: {Global`}

approximate kernel memory recovered: 0 Kb

Out[0]= {CleanSlate`, Global`, System`}

In[1]:= Print[a]


The package should work also if you use version older than 3.0.
