Start with looking up "naming conventions" in VFP Help.
You'll want to add things like comments (IMO, you don't need more than a single * and never comment at the end of a line &&)
Include things like how to indent loops and conditional branching.
You should also use the full command and function names (don't abbreviate to the first four letters)
