Encodes strings of ASCII characters as their hex equivalents, superseded by the builtin filter.hex methods

Description
Encodes strings of ASCII characters as their hex equivalents, superseded by the builtin filter.hex methods
Usage Details

The legacy hex.lua module encodes strings of ASCII characters as their hex equivalents.

This method has been superseded by the filter.hex methods that were introduced in Iguana 5.05.

How to use dbc.lua:

• Add a module called “dbc” to a From Translator component
• Paste the code into the module
• Add `require 'dbc'` at the top of your code
• Use the `query()`, `execute()`, `merge()`, and `close()` methods
