Option _Explicit Keyword(s) of day XXX:

[SMcNeill]

What if your code is a "trade secret" you want to protect, but some reason you have to post it somewhere or you have to share it with someone?

Then either you trust that person and they have the proper clearance to see/edit/access your "trade secret" process, or else you end up going to court over violation of intellectual property rights and forfeiture of any non-disclosure agreement which you signed.  Changing variable names from a readable Screen_Position_X to SPX isn't enough to allow for such to still not be considered a breach of your agreement.

Option _Explicit does not allow one to just change a few names to obfuscate their code so they can get around any sort of "trade secret" clause.  I certainly know any boss that I've ever worked for in my life would have his eyeballs pop out of his head Wile E Coyote style, and then he'd attach the person who suggested the concept to the closest Acme rocket and pair of rollerskates and happily launched them off towards the closest unemployment office.
