Holes - This program will examine the bitmap of a directory device
	and locate regions of unused contiguous storage.
	The program will then display the locations and sizes
	of these regions.
	An optional lower limit can be set so that regions
	smaller than a given size will be ignored.



Usage - This program must be installed to work.

	The command syntax takes one of three forms:
		1)	>HOL			!Finds holes on "SY:"
