I Know I'm to blame - Code repitition

[PaulF]

I am very bad, I don't sit down and do flow charts, I rely on my dwindling brain. However as I fumble along with code I find I end up with lots of duplicated code which I could condense into routines. After I realise my dilemma, I spend hours running through code doing searches on commonalities and grouping things up, only to then generate bugs man made. Is there any magic way to alieviate the problem. As I say I am the one to blame. Thanks

The best way I have found to approach this is to start over again every now and then. If you don't like the paper part of design work, it is the only way.

Also, just grouping things together because the code looks similar is a bad approach. Look at what the function is - if there is a logical function that is used in several places, then that should be a subroutine or function.

Also, try reading a book on structured design. I haven't looked at any lately, but there used to be whole shelves of them at Borders and Barnes and Noble.
