!C Main differences convect3/convect4:
!C	- icbs (input) is the first level above LCL (may differ from icb)
!C	- many minor differences in the iterations
!C	- condensed water not removed from tvp in convect3
!C   - vertical profile of buoyancy computed here (use of buoybase)
!C   - the determination of inb is different
!C   - no inb1, only inb in output
