AMBER: Saving (.)prepin file

I created a prepin file for a benzene molecule using antechamber. I
loaded the force field, modified the missing parameter from the frcmod
file, and loaded the .prepin file as on page 75 of the amber7 manual
as bz.prepin. The last step is to save and create the topology and
coordinate files, upon the command <saveAmberParm BZ prmtop prmcrd>
the error message is:
saveAmberParm: Argument #1 is type String must be of type: [unit]
usage: saveAmberParm <unit> <topologyfile> <coordfile>
Any hint as to how to overcome this problem ?
