Mark,
If I had a 4 to 10 with the step of 2 would I then have a final value of:
12 or 10 ?
4,6,8,10 or would the loop actually stop processing on 12 giving me a final value of
12?
Since it has to check the endvalue and be greater than 10 wouldn't it then have a
counter of a final value of 12? or less than 10 if the counter were -2

Jodi,
1) The final value would be 5.
2) Yes.

I still do not understand what the final value of the IntB would be if it is 1 to 5
and a step 1.
Would The final value be 5 or is it one higher (6). That was the question.
1.Does it end up one or more higher when ending the loop, or is the final count equal
to the 5 if the step is 1.
2. Is 1 to 5 the same as 1 to 5 step 1

A for / next loop is just short hand for a do loop.
for times = 0 to 10 step 2
msgbox times
next times
would give you message boxes saying 0, 2, 4, 6...
times = 0
do until times > 10
msgbox times
times = times + 2
loop
would give you a message boxes saying 0, 2, 4, 6 ...
I think something you are noticing is WHERE in the for next loop the logic
is being checked.
With a do loop you can have:
do until such and such
loop
or
do
loop until such and such
I do see your point - your counter always ends up 1 or more higher
(depending on your step) after it falls out of the loop.
This is okay - you almost never really care what the value is when falling
out of a for / next loop. This is because you usually have some
predetermined number you using. For example, you know there are 100 times
in a list box and you want to process them you would do
For Times = 1 to 100
'processing statements
Next times
More likely you would do this:
For times = 0 to lstItems.listcount - 1
'processing statements
Next times
So you see - you don't care that your times counter gets one past when you
fall out.
In general, if you are counting things up to discover the number that is
there you use a do loop, not a for next loop. Example, how many entries are
in a file on the hard drive called logentries.txt
open "c:\logentries.txt" for input as #1
ctr = 0
do until eof(1) = true
line input #1, linefromfile
ctr = ctr + 1
loop
close #1
msgbox "There are " & ctr & " lines in the file."
You can see, you could never properly process a file with unknown amounts of
data with a for / next loop.
I hope this gives you a little clarity.
