output-number

: Output string of a number involved in number substitution,

consisting of characters such as 0 to 9, #, *, and ., up to 31 characters. The
characters are described in Table 687.

The sub-expression (one digit or digit string) before !, %, or + is not
exactly-matched digit(s) and is handled in a similar way the wildcard (.). These
signs cannot be used alone and must be preceded by a valid digit or digit string.

The dot (.) in the

input-number

and

output-number

arguments is handled in three

ways:

The dot (.) in the

output-number

argument is considered invalid. If you use the

dot-match

command to set the dot match rule to

end-only

(that is, only dots at

the end of the

input number

are handled), the dots in the

output-number

argument are discarded immediately, and the digits which all the dots at the end
of the

input number

correspond to are added to the end of the

output number

Extra dots in the

output-number

argument are discarded. If you use the

dot-match

command to set the dot match rule to

right-left

(from right to left) or

left-right

(from left to right), and the number of dots in the

output-number

argument is greater than that in the

input-number

argument, all digits which the

dots in the

input-number

argument correspond to are selected to replace the dots

in the

output-number

argument one by one from right to left (or from left to

right). The remaining dots (that are not replaced) in the

output-number

argument

are discarded.

Extra dots in the

input-number

argument are discarded. If you use the

dot-match

command to set the dot match rule to

right-left

(from right to left) or

left-right

(from left to right), and the number of dots in the

input-number

argument is

greater than or equal to that in the

output-number

argument, the dot handling

includes two cases:

■

For the right-left dot match rule, digits which the dots in the

input-number

argument correspond to are extracted from right to left according to the
number of dots in the

output-number

argument to replace the dots in the

output-number

argument one by one. The digits that are not extracted in the

input-number

argument are discarded.

Table 687

Meanings of characters in the string argument

Character Meaning

0-9

Digit 0 through 9.

# and *

Valid digit each.

Wildcard, which can match any valid digit. For example, 555.... can match any
number beginning with 555 and ending up with four additional characters.

The character or sub-expression before the sign does not appear or appears
only once. For example, 56!1234 can match 51234 and 561234.

The character or sub-expression before the plus sign can appear one or more
times. However, if the plus sign appears at the head of a number, the number
is an E.164 number and the plus sign itself does not represent a specific
number or number repetition. For example, 9876(54)+ can match 987654,
98765454, 9876545454, and so on, and +110022 is an E.164 number.

The character or sub-expression before the percent sign does not appear or
appears multiple times. For example, 9876(54)% can match 9876, 987654,
98765454, 9876545454, and so on.
