ITS.Is Lastname

NTS.Is Lastname

Test  if the input string is a valid last name

 

 

Intention

 

Conditional Statement. To assess if the input string is a valid last name, observing specific conventions for character content, length, and structure.

•Length Constraints: Ensures the last name is within an acceptable length, typically between 2 to 50 characters.

•Start and End Characters: Checks that the last name starts with an uppercase letter and ends with a letter.

•Valid Characters Set: Restricts valid characters to letters, hyphens, apostrophes, and space characters.

•Proper Use of Hyphens and Apostrophes: Verifies that hyphens and apostrophes are not at the beginning or end and are not consecutive.

•Positional Validation of Special Characters: Hyphens and apostrophes must not be at the beginning or end of the name, nor can they occur in sequence.

 

The ITS. command focuses on the structural validation of a last name, ensuring that it adheres to common naming conventions.

The NTS. command determines that the provided string does not qualify as a valid last name based on the specified criteria.

 

Example Use Case:

 

TST.Generate LastName|GER|$$N02

ITS.Is Lastname|$$N02

 DBP.$$N02 is a valid last name.

ELS.

 DBP.$$N02 is NOT a valid last name.

EIF.

ENR.

 

The result could indicate:

Müller is a valid last name.

 

 

 

 

Syntax
