personally i dont think you're missing much by not having Guiness, but why not just do while copies > 0 no other validation needed, except to ensure the value entered was a number.

I use do...while on occasion. It's actually a useful loop that ensures code is performed at least once. Certainly you can always do the same loop using a standard while loop, but often it increases readability and comprehension.

i've just found other loops more usefull, i understand what they're for, just never found a situtation nwhere they're the best fit, in the above i would have use while copies > 0, and not had to check what the value of copies was as long as i checked the user input to make sure its a number, depending on how they were allowed to enter it. i've known people who have been doing thise for 15 - 20+ years and they have to go out of their way to use one. maybe it got ingrained in my head at some point to not think using post checks, and to always use prechecks..i dont know.

I can probably count on one hand the number of times I have had to use do/while, and probably on all fingers and toes the number of times I used just a while (which correlates almost exactly to the number of times I have had to write a TCP server, and then it still has a goto or 2!).

Yeah - I once had a user backing up their data, every day, to floppy for six months. Then they had a crash and needed to restore and the restore didn't work. I had to go over to see what the issue was...
I Start restore
"Insert Disk 1"
I ask for the first floppy, and insert it...
"Disk 20 of 20: Please insert disk 1 of 20"
I ask for the first floppy..
"Oh, there's only one." says the user.
"But this is disk 20" quoth I.
<snip -="" long="" and="" confused="" conversation="" ensued="">
"So," i calmly stated "when the backup program said 'Insert Disk 2 then press Enter to continue.' you pressed Enter. Then when the message **Warning disk will be Formatted - All data will be lost**', you just pressed Enter again?"
"Yes." replied the user, in a tone which suggested that only a fool would do anthing else. "and the same for disk 3, and 4 ... We thought it was clever to fit all that data onto one disk! Isn't that what formatting means?"
I suppose I should have realised they weren't the smartest bunch on the planet when, in previous years, they had folded an old 5 1/4" diskette in half to send through the post (and stapled a with-compliments slip to it) and seemed surprised that I couldn't read it!

I used to work with a guy who was clever enough to write this:
For i = 1 To 5
If i = 1 Then
...
Else If i = 2 Then
...
Else If i = 3 Then
...
Else If i = 4 Then
...
Else If i = 5 Then
...
End If
Next i
I guess the coder wanted to do something "in five steps". He certainly does.

Maybe there is a i++ in some states in the if blocks to skip steps?

While a select-case statement would probably be better than the cascaded if/else-if, the illustrated construct may not be unreasonable in certain cases where it is expected that the inside of the loop will be pulled out into a separate routine for use as a state machine. Having the code within a for-next loop may be handy during development while the code is being perfected, even if the final construct will be something else.
To be sure, when running on a PC it's often easier to use threads rather than state machines, but state machines can often have a much lower 'footprint'. If an application will require hundreds or thousands of objects each with a multi-way state machine, and all have to be operable concurrently, a select-case state machine may be a reasonable approach. Delegates should be considered as well, since they have some advantages (but also some disadvantages), but state machines are reasonable in simple cases.

Where in the original WTF did it mention a problem that would require State Machines or Threads to solve?

My point was that there are circumstances where code like that illustrated may be useful. While it is true that there was nothing to indicate that such circumstances applied here, I would not wish to condemn code without knowing that such circumstances did not apply.
BTW, another circumstance where such code may be useful is in cases where the loop will evolve into something like:
for i=1 to 5
.. do some stuff in every case
if i=1 then
.. handle first case
else if i=2 then
.. handle second case
... etc
end if
.. do some more stuff in every case
In many circumstances, that style of code could be handled better by putting the different parts into subroutines and just calling them:
everycase_prep()
.. handle first case
everycase_cleanup()
everycase_prep()
.. handle second case
everycase_cleanup()
In some cases, however, the prep and cleanup would need to share many local variables, thus requiring either long parameter lists or awkward class constructs.

I just found this board, and just had to share...
A programmer had the job of writing a routine to perform calculations based upon fees over time (the detail's not important - essentially she needed to know the number of days between two dates, and apply an algorithm something like 'for the first 30 days, a fee of 10c per day, up to 45 days, 25c per day, from 46 through to 100 45c per day)
Now, there's 1001 ways to do it - but I couldn't believe that she produced a huge Cobol program to do it.
It contained a huge array of constants, called January1984, February1984 etc. etc. etc. wach one being the number of days in that month.
Then she had an
If FromDateMonth = "January" and FromDateYear = 1984
Subtract DateDay from January1984 Giving calcDays.
Else If FromDateMonth = "February" and FromDateYear = 1984
Subtract DateDay from February1984 Giving calcDays
etc.
etc.
for every month of every year for about ten years.
THEN she repeated the same set of If's for the end date.
THEN she repeated the same set of If's, in a loop, for each month in between!
I couldn't believe that any programmer could be quite so dumb! When asked, she just said she couldn't think of a better way of doing it! (Oh, it had taken her nearly two weeks to do - I had estimated a day, and allowed her a week, as she was new to the company, though not to Cobol)
And sure, I should have looked at the code before she got so far - but she wasn't a junior (and she never became a senior)
(Oh and excuse my code - it's been a long time since I did Cobol and can't really remmeber the syntax)
