Arithmetic operations

ADD

To add value 1 to value 2.

SUB

To subtract value 2 from value 1.

MUL

To multiply value 1 by value 2.

DIV

To divide value 1 by value 2.

Digit string operations

CATR

To concatenate the digit string of value 2 to the right end of value 1 digit string.

For example, if you configure set digits = A CATR B, where variable A value is 2345 and variable B value is 1, the Routing Core Server assigns the value of 23451 to digits in the digit buffer.

CATL

To concatenate the digit string of value 2 to the left end of value 1 digit string.

For example, if you configure set digits = A CATL B, where variable A value is 2345 and variable B value is 1, the Routing Core Server assigns the value of 12345 to digits in the digit buffer.

MOD10

To check string lengths using the Modulus 10 algorithm. You can also use the MOD10 operation to validate account numbers and credit card numbers.

After performing the MOD10 operation, the Routing Core Server assigns the following value to digits from the digit buffer:

• 0: Digits in value 1 match the length specified in value 2 and passed the Modulus 10 validation.

• 1 through 9: The digit string, account number, or credit card number is complete but not valid.

• #: The digit string, account number, or credit card number did not pass the Modulus 10 validation. For example, the digit string in value 1 does not match the length specified in value 2.

SEL

To select the rightmost number of digits specified in value 2 from the digit string of value 1.

For example, if you configure set digits = A SEL B, where variable A value is 2345 and variable B value is 2, the Routing Core Server assigns the value of 45 to digits in the digit buffer.
