What helps me in bigger programs is to explain what each routine does
right after I declare it, then follow that logic with little comments.
That's pretty much how all my code ever looks. Although for
distribution, I have a little utility that strips any comments
starting on the first line, which helps reduce the size of my files.
(Sometimes over 1/2 my code is comments, heck look at Win32Lib, it's
nuthin but comments!)

Example: (I'm using this in an app I'm writing)

global function dayOfWeek( integer pMonth, integer pDay, integer pYear )
--  This function determines the day of the week given
--  a date in the form Month, Day, Year. I believe this
--  formula may be more accurate than Junko's, or I'd
--  be using Junko's instead. :)
--
--  Step 1: Take the last two digits of the year and add 1/4.
--  Step 2: Determine month code.
--  Step 3: Add year, month code and day
--  Step 4: Take remainder of seven.
--
--  The result is the day of the week (starting with Monday)

    integer lCode, lResult

    -- subtract 100 until pYear is less than 100
    while pYear > 100 do
        pYear -= 100
    end while

    -- add 1/4 to the year
    pYear += floor( pYear / 4 )

    -- determine month code, MONTH_CODE
    -- is declared else where in our code
    lCode = MONTH_CODE[ pMonth ]

    -- add the values
    lResult = pYear + lCode + pDay

    -- get remainder of seven and add 1
    lResult = remainder( lResult, 7 ) + 1

    return lResult
end function
