JOIN String Functions by Charles Carroll
The various string functions can be used
interchangeably often. We will write the same script using SPLIT, REPLACE and JOIN to
demonstrate all 3 functions and how they often are used for similar tasks. However, your
programming situations may be especially suited for 1 out of 3 of the functions.
JOIN(array,delimiter)
takes an array and converts it to one string with delimiters.
The user can enter a state or multiple states. We write the program using
the JOIN function to demonstrate how this function can be used.

There are many worthy charities!!. But perhaps help starving children in Africa or South America AND help Charles too.
a $5 tip buys him lunch at McDonalds,
a $20 tip buys his kid Hitoshi a new computer game,
a $39 tip buys his daughter Michiko a few nice outfits.
See our donor list.
