   zero page allocation for Forth

   If you needed 141 bytes of zero page on a C-64, what addresses would you use?    
   BASIC is switched out, Kernal is still switched in, so anything BASIC uses can   
   be reallocated.  Having it all be contiguous so I can go in and out of BASIC   
   is important too.   
      
   On a PET (4.0 ROM) I'm just using $00-$8C (everything below jiffy clock) and   
   there's a little ML routine ('aloha') to swap the half page in and out, but I   
   want to port PETTIL to the C=64
