 TRANS routines that may be used: TRANS1, TRANS4, TRANS6

 Basic PK parameters with TRANS1:

   K (rate constant of elimination)
   K23 (rate constant from central to peripheral 1)
   K32 (rate constant from peripheral 1 to central)
   K24 (rate constant from central to peripheral 2)
   K42 (rate constant from peripheral 2 to central)
   KA (rate constant of absorption)

 Basic PK parameters with TRANS4: (See TRANS4).

 Basic PK parameters with TRANS6: (See TRANS6).

 Additional PK parameters:

   S1 - Scale for depot compartment
   S2 - Scale for central compartment (also called SC)
   S3 - Scale for peripheral compartment 1
   S4 - Scale for peripheral compartment 2
   S5 - Scale for output compartment (also called S0)
   F1 - Bioavailability for depot compartment
   F2 - Bioavailability for central compartment
   F3 - Bioavailability for peripheral compartment 1
   F4 - Bioavailability for peripheral compartment 2
   R1 - Rate for depot compartment
   R2 - Rate for central compartment
   R3 - Rate for peripheral compartment 1
   R4 - Rate for peripheral compartment 2
   D1 - Duration for depot compartment
   D2 - Duration for central compartment
   D3 - Duration for peripheral compartment 1
   D4 - Duration for peripheral compartment 2
   ALAG1 - Absorption lag for depot compartment
   ALAG2 - Absorption lag for central compartment
   ALAG3 - Absorption lag for peripheral compartment 1
   ALAG4 - Absorption lag for peripheral compartment 2
   F0 - Output fraction (also called F5, FO)
   XSCALE - X parameter

 Steady-state subroutines:  SS12, SS6

 Other required user or library routines:

 Library:  EXP3  EXP4

 Notes:

 1    Analytical second derivatives used with the Laplacian method  are
      not  obtained with ADVAN12.  Numerical second derivatives must be
      used.

 2    Can be greatly speeded up if calls to PK can  be  limited.   (Use
      CALLFL=1  in  $PK to call once per IR, and use the CALL data item
      to force additional calls  if  and  when  necessary;  e.g.,  when
      covariates used in the PK model change.)
