Are there different levels on indentation? If so, wouldn't the program run differently when different lengths of indentation is used? Or are you speaking only of representation for reading purposes rather than for actual code writing? Thanks. --- Be positive!

This may be controversial. Although four spaces is the most common indentation, I suggest two spaces per indentation level will work better especially for email. Two and four spaces are both common standards, but four spaces eats too much page territory. Richard
