  Possible Instructions

  Description
 
  Pops the top element off the stack and checks whether or not it is equal
  to zero. If it is not equal to zero, control jumps ahead <n> bytes or to
  location S. Otherwise control continues with the next instruction.
 
  Pseudocode equivalent:
 
  if (popW() != 0)
  pc += <n>;
 
  This instruction is generated by the following example:
 
  if (wTest == 0)               /* generates JnzW<n> */
