 MEANING: Marks the beginning of abbreviated code for the PRED routine
 CONTEXT: NM-TRAN Control Record

 USAGE:
 $PRED
 abbreviated code

 DISCUSSION:
 The $PRED record is used to model values for the DV data items.  It is
 NOT used with PREDPP (but (See $ERROR).  General rules for abbreviated
 code  are documented elsewhere (See abbreviated code).  Specific rules
 for $PRED follow.

 ASSIGNMENT AND CONDITIONAL STATEMENTS

 Left-hand quantities in assignment statements:

   Y (Required. The modeled value for the dependent variable under  the
   statistical model.)

   PRED-defined items.

 Right-hand quantities in assignment statement and in conditions:

   Data item labels specified on the $INPUT statement.

   THETA(n).

   ETA(n)  (Used if the data are population or single-subject data, and
   in the latter case can be coded ERR(n).)

   EPS(n) (Used if the data are population, and can be coded ERR(n).)

   PRED-defined items that appeared earlier  as  left-hand  quantities.
   This includes Y.

   NEWIND
    Same as the NEWIND argument passed by NONMEM to PREDPP.
    NEWIND=0:  First  record  of  the data set.  THETA value may differ
    from value at last call with this record.
    NEWIND=1: First record of the data set, THETA value does not differ
    from  value at last call with this record, and PRED is nonrecursive
    (see I_REC), or,
    First record of a subsequent individual record.
    NEWIND=2: Subsequent data record of an individual record.

   NEWL2
    NEWL2=1: First record of an L2 record.
    NEWL2=2: Otherwise.

   ICALL
    ICALL=0: Run initialization.
    ICALL=1: Problem initialization.
    ICALL=2: Normal call.
    ICALL=3: Problem finalization.
    ICALL=4: Simulation.
    ICALL=5: Expectation.
    ICALL=6: Data Average.
    Special rules apply to blocks of abbreviated code that are executed
    when ICALL is not 2.
    (See initialization, finalization, simulation).
    (See expectation, data average).

   Variables in Fortran modules
    Certain  variables  in  FORTRAN  modules  can  be used.  (See Vari-
    ables_in_modules)

 Forbidden Variable Names:

 DATREC INDXS G H DADT(n) A(n) E(n) P(n)

 PSEUDO ASSIGNMENT STATEMENTS
   COMRES=-1
 RECORD ORDER:

 Follows $SUBROUTINES and $INPUT
