Re: should i write keywords uppercase?

You likely will get a variety of philosophies in replies here. Each
programmer seems to develop his own style. Some outfits impose coding
standards for projects, for consistency, which is good. In any case,
one point to consider is that comments ought to stand out from code,
and plenty of good commenting is quite desirable. I wouldn't recommend
bulk paragraphs providing explanations that really belong in external
documentation, but enough clear commenting to allow someone reading the
code six months later (such as yourself) to know how to use a
subprogram, to follow the flow of logic and calculations, and to
connect parts of the code to pertinent external documentation.
Programming is a great investment in time, and a great deal of that
time can be lost later when the code must be reused or at least fixed
and commenting is missing or poorly done.

In most of my own code, I have used upper case for code and lower case
(with capitalization as appropriate) for comments. Whatever you work
out for yourself should at least pass the test of readability.

I imagine you'll also get advice on other readability issues, such as
whether or not an END IF should be coded without the space between the
END and IF and whether it should be indented to the same level as the
code paragraph it ends or line up with the original IF statement.
