The way to do what you want is to make a delayed assignment to the OwnValues of var that overwrites itself on execution. (MMA 5.2 Kernel) In[1]:= var:=var=Table[Random[Integer,{0,3}],{param}]; param=3; (MMA 5.2 Kernel) In[3]:= ?var Global`var var:=var=Table[Random[Integer,{0,3}],{param}] (MMA 5.2 Kernel) In[4]:= var (MMA 5.2 Kernel) Out[4]= {0,0,0} (MMA 5.2 Kernel) In[5]:= ?var Global`var var={0,0,0} (MMA 5.2 Kernel) In[6]:= var (MMA 5.2 Kernel) Out[6]= {0,0,0} On 4/19/07, zac <replicatorzed at gmail.com> wrote: > Dear Group! > > My target is to define the value of 'var' in terms of the value of > 'param'.
