There is an equivelent of the cd command. It's called PREFIX.

PREFIX /DIRECTORY/SUB.DIRECTORY switches to a subdirectory not in the current.
PREFIX DIRECTORY switches to a subdirectory in the current.
PREFIX/ returns to the DOS 3.3 style (PREFIX S3,D2 for Aux RAM, f.e.)

Is that really included with plain-vanilla DOS 3.3? I always thought that
the FP/INT command was an add-on thing.
