  Description
 
  Transfers the value on the stack to the specified frame variable and
  pops the value off of the stack.
 
  Pseudocode equivalent:
 
  // when <n> is a implied number #
 
  *(bp - fs - (2 *  #)) = Pop<t>();
 
  // when <n> is a byte <b>
 
  *(bp + (2 * (<b> | 0xff00))) = Pop<t>();
 
  // when <n> is a word w
 
  *(bp + (2 * w)) = Pop<t>();
 
  Assigning a value to any frame variable will produce this instruction:
 
  w1 = 25;            /* generates STF<n> */
