  Description
 
  Loads the value of the specified local variable or function parameter
  onto the stack. A negative value for <n> addresses a local variable, and
  a positive value addresses a function parameter.
 
  NOTE: When Ldf<t>b is generated, the byte parameter is assumed to be a
        negative value. Thus, it refers only to local variables.
 
  // when <n> is a implied number #
 
  Push<t>(bp - fs - (2 *  #));
 
  // when <n> is a byte <b>
 
  Push<t>(bp + (2 * (<b> | 0xff00)));
 
  // when <n> is a word w
 
  Push<t>(bp + (2 * w));
