I have the following?

b = ["StringC"]

How to I subtract the two arrays so I have a new array with the
following?

result = ["StringA", "StringB"]

Thanks

You've almost answered your own question:

a = ["StringA", "StringB", "StringC"]

=> ["StringA", "StringB", "StringC"]

?> b = ["StringC"]
=> ["StringC"]

a - b

=> ["StringA", "StringB"]

Hi Brian,

if you have the following arrays:

a = ["StringA", "StringB", "StringC"]

b = ["StringC"]

should do the following:

c = a-b
c = ["StringA", "StringB"]

Bye.

Sorry, about my english Tarzan...jeje...
