You know, Rex, since Dave re-awoke the whole issue, I decided to revisit it. So therefore (and I had put this in a previous post in this thread) here is the full and complete code from a routine I simply called "Timer Sample That Worked.btm":
Code:
@Echo Off
SetLocal
Do StartTime In /P Timer On /2()
Set I=
Do While %I LT 10000
Set /A I+=1
EndDo
Do EndTime In /P Timer Off /2()
@Echo Start Time: %@Word[3,%StartTime]
@Echo End Time: %@Word[3,%EndTime] Elapsed Time: %@Word[5,%EndTime]
EndLocal
Quit 0
The above is the complete contents of the batch file, unmodified in any way.
Here are the results of running the above batch file:
Code:
[Z:\]"Timer Sample That Worked"
Start Time: 23:22:31
End Time: 23:22:35 Elapsed Time: 0:00:03.86
Again complete and unmodified in any way.
I really don't think it's necessary to say that it worked fine, but it obviously did without any reservations whatsoever. (And if I double the loop count, the elapsed time approximately doubles, as expected.)
However, if the batch file looks like this:
Code:
@Echo Off
SetLocal
Do StartTime In /P Timer On /2 ()
Set I=
Do While %I LT 10000
Set /A I+=1
EndDo
Do EndTime In /P Timer Off /2 ()
@Echo Start Time: %@Word[3,%StartTime]
@Echo End Time: %@Word[3,%EndTime] Elapsed Time: %@Word[5,%EndTime]
EndLocal
Quit 0
Here's the output, again unmodified in any way:
Code:
[Z:\]"Timer Sample That Worked"
Start Time:
End Time: Elapsed Time:
This clearly
doesn't work at all, and the
only difference between this and the first version (above, of course) are the spaces between the "/2"'s and the open parenthesis.
Bottom line: Since complete code above is shown above
in full without
any modification(s) of
any kind whatsoever, I challenge you to copy it out of the above and put it in a batch file that you then run yourself so that you can prove to yourself that what I say is completely true in full without any modifications or exceptions of any kind whatsoever.

P. S. And yes, I'm a little irritated (at myself, mostly) that you managed to convince me that what was, in fact, provably true was not true. (And, as I said, I had five .btm files that used that technique without any issue(s) whatsoever other than the slight syntax weirdness I asked about as an "just out of curiosity" question in my original question that started this thread.)
