>o Command and Functions are always in CAPS.

Basically, the previous rule is the only one that I don't like.

I would add:
- Always use () for methods, func/procs and events.
- Always use [] for arrays.
- Declare all locally used variables as local/private at the begining of each func/proc/method. Don't declare variables in other places inside funcs/procs/methods (ie: inside loops, ifs, etc.)
- Use FOR ... ENDFOR not FOR ... NEXT ... (this is really a matter of taste, but ENDFOR is more in the FoxPro style)
- Don't use "&&" comments.
- Don't write code lines longer than 50-60 chars.
- Parenthesize each condition in composed logical expressions.
- Don't use square brackets for character strings unless you need it.

And for index names: if the index expression is a single field, than the name of the index is the same as the name of the field.
