! 1. Updates
!
! 100.04, Nov. 92: Filename of plotfile will be given by user
! 30.70, Nov. 97: Arguments BOTLEV and WATLEV added
! 32.02, Feb. 98: 1D version introduced
! 30.72, Feb. 98: Introduced generic names XCGRID, YCGRID and SPCSIG for SWAN
! 30.82, Apr. 98: Removed reference to commons KAART and KAR
! 30.90, Oct. 98: Introduced EQUIVALENCE POOL-arrays
! 30.81, Nov. 98: Replaced variable STATUS by IERR (because STATUS is a
! reserved word)

!
! 4. Argument variables
!
! i BOTLEV: Bottom levels 30.70
! i WATLEV: Water levels 30.70
!
