1 FHD
	FHD is a program to list the file header of a given file
 
	Primary purpose is to list all the pieces of the file
	to determine how fragmented the file is if it is a large
	data file, and to determine which absolute blocks on the
	disk the file occupies, (if troubles occur with the disk)
 
	After listing routine information from the file header, fhd
	lists each piece of the file, reporting on:
 
	Number of blocks  (decimal)
	First block # (absolute disk block number, 2 word, octal)
	Last block #  (absolute disk block number, 2 word, octal)
 
	Fhd also reports if the header had to be extended (by using
	an extension file header) and lists the unique file id (FID)
	for the extension file
 
	calling proceedure
	MCR>FHD nnnnnn,mmmmmm		where
	
		nnnnnn,mmmmmm is the file's (unique) FILE ID
		(obtained via a PIP or SRD directory using the "/FU" switch)
