      SUBROUTINE SIMSET(NCH,NB,HCYC,NASMB1,ASMB1,BURN,IFUEL,ZONE,NAME,
     > BURNUP,FMIX)
*
*-----------------------------------------------------------------------
*
*Purpose:
* Set the burnup and fuel type of a group of assemblies at positions
* ASMB1.

*
*Parameters: input/output
* NCH     number of assemblies or number of quart-of-assemblies.
* NB      number of axial burnup subdivisions in an assembly.
* HCYC    name of cycle.
* NASMB1  number of assemblies to set.
* ASMB1   group of assembly names, as defined in the fuel map, to set
*         at specific burnup or fuel type.
* BURN    burnup in MW-day/tonne. Burnup must be set if .ne.-999.0.
* IFUEL   fuel type. Fuel type must be set if .ne.0.
* ZONE    default assembly or quart-of-assembly names as defined in
*         the fuel map.
* NAME    names of each assembly or of each quart-of assembly during
*         a refuelling cycle. All quart-of-assembly belonging to the
*         same assembly have the same name.
* BURNUP  burnups during a refuelling cycle. A value of -999.0 means
*         a non-initialized value.
* FMIX    assembly types after refuelling.
