Does PISO algorithm work with interfoam in openFOAM 2.1.0?

I have been using openFOAM to simulate a dam break problem. The issue is that i used PISO algorithm in the "fvSolutions" file and used interFOAM as the solver. When I tried to run the program, an error message crept in as follows:
" keyword PIMPLE undefined in the file ..\fvsolutions"
But when I tried to run the same code in FOAM 1.7.x, I could see the results. What could possibly be the reason?
Thank u in advance

Solver structure changed from 1.7.x to 2.1.x, and PISO was replaced by PIMPLE. Adapt your case to the new solver - see the interFoam tutorial as a guideline.

just change PISO for PIMPLE within fvSolution and everything will run again. Furthermore, PIMPLE is a merging of PISO and SIMPLE algorithms, if you do not specify any overrelaxation factor you will still use PISO: when the simulation starts you can read - PIMPLE: Operating solver in PISO mode
