BASIC is a very good language. As a matter of fact, I do most of my programming in either C or VBASIC! It is nearly plain English! However, it is hard to write long programs in BASIC without making it too confusing.
The revolutionary language would be when:
To drive a motor:
change [motor name] speed to [high/8 bit integer]
To turn on an LED:
turn on [led name]
To do a complex calculation:
[variable name] equals the (square root of 64 plus 8) divided by two
You probably get the gist of it. Preserve all grammar and make it so that pseudocode is the actual code

. That would be the end of programming language development, especially when we get it to run directly on the processor hardware like assembler!
