In a quick search, I couldn't find the earliest reference to the ABC
language, so you may be correct; however, the Occam programming language
also uses indentation to indicate code blocks.  I started using Occam in
1984(maybe - definitely by 1985).  I believe that the first Occam
implementation was developed by 1982.

By the way, I prefer Occam's indentation rules.  Two spaces, no tabs.
