 The task UIC is used to change your current User Identification Code.
 It can be used to change your UIC to a certain value (e.g. "UIC 1,2"
 sets your UIC to [1,2]), or set your UIC to a certain account's UIC
 (e.g. "UIC JUNK" sets your UIC to [377,377]), or display your
 current UIC (e.g. "UIC").
 
 When you use an account name, the password is optional.  If it is
 specified, it is checked.  It is only required when there are more
 than one accounts with the same name, but different passwords, and
 you do not want the first one in the account file.
 
 When the account file is used, the login SY: defined in the account
 file is assigned to your SY: and displayed on your terminal.
 
 Examples:
 
 	>UIC			Displays your current UIC
 	UIC=[377,377]
 
 	>UIC 123,321		Sets your UIC to [123,321]
 
 	>UIC JUNK		Sets your UIC and SY: as defined for
 	ASN LB:=SY:		account "JUNK"
 	UIC=[377,377]
