Pattern Interpretation
A B C
“Standard” 3-character address, shown here for reference. All the characters in this
word must be evaluated
A B ?
A ? C
? B C
“Standard” “wild-1” address word. Indicates that only the positions occupied by other
characters (“A” and “B”) need be evaluated: the position occupied by the “?” symbol
can be ignored (ignored in this context means that any valid character is accepted)
A ? ?
? B ?
? ? C
“Standard” “wild-2” address word. Indicates that only the position occupied by an
character (“A”, “B” or “C”) need be evaluated: the positions occupied by the “?” symbols
can be ignored
? ? ?
“Standard” “wild-3” address word. Indicates that all of the three positions in this word
can be ignored
A B @
“Stuff-1” reduced address field, shown here for reference. Only the first two characters
in this word must be evaluated
A ? @
? B @
“Wild-1” “stuff-1” address. Only the character “A” or “B” in this word must be evaluated
? ? @
“Wild-2” “stuff-2” address. Only the character “A” or “B” in this word must be evaluated
A @ @
“Stuff-2” reduced address field, shown here for reference. Only the first character in this
word must be evaluated
? @ @
“Wild-1” “stuff-2” address. Only t
he first character in this word must be evaluated, and is
ignored
@ A B
“Double selective AnyCall” address word, shown here for reference: only the last two
characters in this word must be evaluated
@ A ?
“Double selective AnyCall” “wild-1” address word: only the middle character “A” in this
word must be evaluated
@ ? B
Not permitted. Use “selective AnyCall”
@ ? ?
Not permitted. Use “global AnyCall”
@ @ A
“Selective AnyCall”: see Table C-1
@ @ ?
“Global AnyCall”: see Table C-1

individual or to a select group.
The global AllCall address is @?@. As a variation, the calling station can also use selective AllCall.
Basically, the selective AllCall address is identical in function to the global AllCall, except that it
