  Syntax
 
  JltW<n>
 
  /* Branch on Less Than */
 
  Possible Instructions
 
  JltW3, JltWb
 
  See: ◄P-Code Operands►
 
  Description
 
  Pops two values off the stack and checks to see if the second is less
  than the first. If it is, control jumps to location S. Otherwise
  processing continues with the next instruction.
 
  Pseudocode equivalent:
 
  w2 = popW();
  w1 = popW();
  if (w1 < w2)
  pc += <n>;
 
  This can be generated by the following:
 
  if (w1 >= w2)                 /* generates JltW<n> */
