WHO VERB
			--------



	The WHO verb allows a user to find the UIC, default device and 
	default directory for a given username on all nodes.

	Format:

	WHO username

	Specifies the username to be searched for. The username specified can
	be complete or a subset such as the following:

	WHO te

	This will display all occurances of usernames starting with te.
	NO wildcard specifications are allowed in the username.


	/UIC=

	Allows a search by specifying the UIC instead of the username. The UIC
	value must follow the standard VMS UIC format of [###,###] but no 
	leading zeros are necessary.

	Wildcard searches are allowed on either the group number or member 
	number.

	Such as:

	WHO/UIC=[20,*]  which will find all occurances of a group number of 20
	on all nodes.

	or

	WHO/UIC=[*,20] which will find all occurances of a member number of 20
	on all nodes.

	The /UIC qualifier cannot be used with a username specified.



	The WHO verbs works by reading the file SYSUAF.DAT. SYSUAF.DAT
	supports indexed reads of the username, total UIC and member number 
	of the UIC. It does NOT	allow indexed reads of the group number. 
	This requires a sequential read of the file. This would take TOO much 
	time when considering how much SYSUAF.DAT is accessed by the cpu. 
	Because of this, I use a copy of SYSUAF.DAT to do my sequential reads. 
	As part of the nightly operator batch job we copy SYSUAF.DAT into
	SYSUAF.TMP. Therefore, all queries made on group number will be at 
	most 1 day old.
									
	Macro program are necessary because the	UIC keys are either 2 or 4 
	byte UNSIGNED values. I'm not aware of a way to declare that in a 
	FORTRAN program.
