lcChars = "abcdefghijkmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890" + IIF(llIncludeSymbols,"!@#$%&*+-?","") + lcAdditionalChars

Rick, I assume the missing lowercase "L" an omission?

Thanks.

Actually - no 😃

The l is left out because it's often confused with 1. These values are often used as validation values and for that reason they should also be easily readable.
