null Object
null Object
A null object type is used as the object type in commands that do not require you to 
specify a particular object type. The null object type is not an actual object type: 
“null” is a term used to represent the absence of an object type in the command. If an 
SCF command supports the null object type, you can issue it without specifying an 
object type. The null object type has no hierarchical relationship to any of the other 
object types that OSI/MHS supports.
For Compaq OSI/MHS, the NAMES and VERSION commands support the null 
object type. The NAMES null command refers to a collection of object types; for the 
VERSION null command, the object type is irrelevant.
The object name for the null object type must identify the MHS manager, $ZMHS.
Examples of null object names include:
VERSION $ZMHS
NAMES $ZMHS
Wild-Card and Special Characters
SCF allows the use of wild-cards and special characters when issuing commands. You 
can use wild-cards in the following ways:
•
In object names, to allow wild-card matching of zero or more characters.
•
In O/R name attributes within ADD and ALTER commands, to indicate “not used.”
•
In the X121-ADDR and NUMERIC-USER-IDENTIFIER O/R name attributes of 
the ADD APPL, ALTER APPL, ADD ROUTE, and ALTER ROUTE commands, to 
allow messages to be routed to partially wild-carded or fully wild-carded addresses.
Wild-Card Notation in Object Names
You can use wild-card characters in object-name specifications to match zero or more 
characters. Two wild-card characters are valid:
1. An asterisk (*) can substitute for zero or more characters. For example, you can use 
it to find all objects whose names begin or end with a certain sequence of characters, 
regardless of the number of characters following or preceding the sequence you 
specify.
2. A question mark (?) can substitute for exactly one character. You can use it to find 
all objects in which the names are the same length but which differ by one character 
in the same position. 
Note. The asterisk (
*
) is used in all three kinds of wild-carding, but the notation and the results 
differ for each situation. Be sure you are using wild-carding correctly for the task you want to 
accomplish.
