   Dear Albert and all,   
      
   In fact I did that Albert; even more than your 20 years ago and I am not a   
   masochist :)   
   I began using Maple at the beginning of the '90 (Maple V.2) and Mathematica in   
   1990   
   (release 1.1.a).   
   And I  still use them.   
   I am not a CS guy/geek at all , I am a retired mathematician and I do enjoy   
   playing   
   with that 2 softwares.   
   Moreover the "Personal/Home" editions are pretty cheap.   
   Kind regards to all,   
   JMC (Jean-Michel)   
   PS: Don't take care of the so-called email you see regarding me, this is a   
   fake.
