 MEANING: TOL subroutine
 CONTEXT: User-supplied subroutine; for use with PREDPP

 USAGE:
 SUBROUTINE TOL(NRD)
 DIMENSION NRD(*)

 DISCUSSION:
 The TOL subroutine is called by PREDPP only once at the start of a run
 when either ADVAN 6, 8, 9, or 10 is used.

 Output argument:

  NRD(I)
      The number of digits that are required to be accurate in the com-
      putation  of the drug amount in compartment I, i.e., the relative
      tolerance.  ADVAN9 has the capability of using  different  values
      of  NRD for different compartments.  However, all the other ADVAN
      routines requiring TOL take the relative tolerance to be the same
      for  all compartments; NRD(I), I > 1, is ignored, and only NRD(1)
      is used.

 When NM-TRAN is used, this information is supplied by either  the  TOL
 option of the $SUBROUTINES record or the $TOL record.
