To add a new waveform to an existing algorithm "aaa", category "ccc"

 1) Define waveserver id using one of the following:
      #define T_aaa_xxxx    CTA_ccc(nn)
      #define IST_aaa_xxxx  ISTA_ccc(nn)
      #define FST_aaa_xxxx  FSTA_ccc(nn)
      #define E_aaa_xxxx    EA_ccc(nn)
      #define S_aaa_xxxx    SA_ccc(nn)

 2) Fill-in archiving information in appropriate array.  Typically:
      Targets(Continuous,IntStep,FltStep)   aaa_target_info[]
      PointerTargets               aaa_?????_info[]
      Error                        aaa_error_info[]
      ShapeVectors                 aaa_shape_info[]
      Command(ctrl output)         aaa_cmd_info[]

    Note: "inherent number" and "physics zero" not used on NSTX.

 3) For target waveforms:
    o Create waveform description for waveserver:  the big
      long struct, which includes parameters for editting in IDL.

    o aaa_vectors()
        - Add case to convert waveserver vertex to r/t target val.
          Note: uses "waveform name" from waveform description.

    o aaa_vertices()  <optional>
        - Add case to provide initial set of vertices for
          un-initialized waveform only.

That's it.  Use vectors within realtime routines:
       {
        val1 = targets[T_aaa_VALUE1-1];    /* remember the "-1" ! */
        val2 = targets[FST_aaa_VALUE2-1];
        ival = istargets[IST_aaa_INTVALUE-1];
        errors[E_aaa_ERRVAL-1] = errorValue;
        shape[S_aaa_COMPUTED-1] = computedValue;
       }
