!  PURPOSE:
!
!  Program to read history data dump from ARPS and convert it
!  into another format.
!
!  Parameters grdin,basin,mstin,rainin,icein,trbin are read in from
!  the data file itself, therefore are determined internally.
!  Arrays that are not read in retains their initial zero values.
!  These parameters are passed among subroutines through
!  a common block defined in 'indtflg.inc'.

!  AUTHOR: Ming Xue
!    8/10/1992
!
!  MODIFICATION HISTORY:
!    Consolidated version for ARPS 3.1 release.
!

!
!    2000/04/17 (Ming Xue)
!    Added an option that allows one to specify input history data
!    at a constant time interval.
!
!    2000/05/19 (Gene Bassett)
!    Converted to F90, creating allocation and main subroutines.
