CF or Let, that is the question?

While learning about building a Let () statement, it occured to me there is a cross over with Custom Functions!


Given the following rules, which is best suited to the task (Let or CF)?


Rules are as follows:


1st 3 letters of code are 1st letters of each word in Co. name

last 2 letters of Code are 1st 2 letters of City

exclude suffixes (i.e. Inc, Co, Ltd...)

consider hyphen as text separator


if Co. name is 1 word (i.e. Hertz),

use 1st 3 letters of Co. name (i.e. HER)

if Co. name is 2 words (i.e. 4 Sale),

use 1st letter of each word in Co. name (i.e. 4S)

if Co. name is 3 words (i.e. Key-Point Transport),

use 1st letter of each word in Co. name (i.e. KPT)

if Co. name is >3 words (i.e. Jolly Green Giant Cannery),

use only 1st letter of 1st 3 words in Co. name (i.e. JGG)


duplicate Co. name (i.e. Hertz),

use same (i.e HER) if City is different, as this will still produce a unique Code

duplicate Co. name (i.e. Hermans),

use next available consonant (i.e HEM)



if City name is 1 word (i.e. Brampton),

use 1st 2 letters of City name (i.e. BR)

if City name is 2 words (i.e. Los Angeles),

use 1st letter of each word in City name (i.e. LA)

if City name is >2 words (i.e. Los Palmas Orianna),

use only 1st letter of 1st 2 words in City name (i.e. LP)


duplicate City name (i.e. Brantford),

use next available consonant (i.e BN) if Co. Name is same

- Hertz, Brampton = HERBR

- Hertz, Brantford = HERBN

- Hertz, Bramalea = HERBM

- Hertz, Brandon = HERBD


In the event a city runs out of consonants,

add a 6th character (1-9 or reverse alpha z/y/x/w/v/u...)


Ultimately, I hope to build the sample in both, a Let () statement and as a Custom Function!
