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.

Wow...
Just wow...
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)

I bet you she is not taking leap years into account.

It is a good thing she did not try to take into account that years ending in hundreds area not, but thousands are. The control code would have been smaller, but the array would have had 12000 entries.

I'm pretty sure that, given thetime, she would have!
And the actual calc is that 'century years' are leap years when divisble by 400 - so 2000 was, but 3000 isn't

It does look like she was trying to be very through, so I am not suprised that she accounted for leap years. What this really points out is that it is not enough for a programmer to be able to write code that works; we also have to be able to come up with fast and efficient ways to solve problems.

Probably - though I seem to rememebr a 32 character limit on field names in Cobol - so could have been the full month name and year

Here's a gem I found in some C++ legacy Windows code I am starting to have to maintain:
if (hWnd ? hWnd == pWndAppts->m_hWnd : pWndAppts)
pWndAppts->DeleteSelected();
else if(hWnd ? hWnd == pWndNotes->m_hWnd : pWndNotes)
pWndNotes->DeleteSelected();
pWndNotes and pWndAppts are class pointers (the exact specifics are unimportant). hWnd is, well, an HWND.
Note how nothing checks to be sure pWndNotes or pWndAppts are not NULL (until it is too late).
Someone obviously thought they were very clever.

Without knowing the code, their could be the situation that pWndNotes or pWndAppts cannot be NULL if hWnd is not NULL. The converse is not true, hence the extra check.

That might be possible. I still have not gotten familiar enough with the code myself to say for sure, yet. I still think it would not have killed them to use a few more lines of code and written it a bit less obtusely.
