when I was mid-BS (ahem) in CS, I used to write all my programs "top down"; just create a bunch of function/procedure names that'd handle the problem and pencil in the loops (on the backs of output pages, w/ a couple of sheets for 'global' vars and page for function prototypes, details to be filled in later). As a mid-level programmer now, performance is so rarely a concern (what I write runs less often (e.g. daily) than its worth to squeeze (or 'bum') any extra speed out of it0) that the value of a clean loop calling meaingfully named functions outweighs any loss in the internal context switches etc.

Keeping the flow clean and localizing the gritty details makes life much easier, and makes the final program that much more maintainable: its way easier to rewrite &Get_Image_Path to handle the addition of a separate image server box than to go back and find and handle all the spots that were calling "Get_Image_Path($case_number, $document_number)"
