Still problems with pbm programs

[robert atnip]

Im trying to convert some files from Harvard Graphics (Harvard Graphics is on a dos machine) over to raster images so I can print them on my Tektronix 4696 
printer.  Im trying to use the tifftopnm program in /grass/4.1/pbmplus/pbm
directory, the I want to use pnmtorast, but I cannot figure out how to properly 
use the commands, please help if you know anything about these commands :
