if 20070323 LSS 20070423 @Echo good!!

Such a simple command, but it just doesn't output the "good!" character. I looked at the help, and string1 LSS string2 seems to only compare strings. Then, if I want to compare two numbers, how should I do it? I searched the forum, but there seems to be no post about this. Please ask the expert to help, thank you.

That code can output good!! here for me.

Hey, strange. Running it alone is okay, but putting it in a bat file doesn't work.郁闷. Is there any expert to answer?

I just saved it as a bat file and ran it...

It works under XP, but not under 2000. It's frustrating.

Maybe 2000 is treating it as a date. Try replacing LSS with GTR. If it shows GOOD, it means it's handling it as a date. If there's an error, look for other reasons. I don't have 2000, so I can't test.

I made a mistake. The above statement is okay, but actually what I want to compare is like this:
if 20070323000000 LSS 20070423000000 @Echo good!!

There are 6 zeros after the date format. It's a log generated by some software, in the format of date + 6 zeros, as above. At this time, it can't be compared in size. I have tested, it seems that it only supports up to 10 digits. Higher than that can't be compared...

Such a large number is being processed by P and cannot be used for comparison or calculation, exceeding the range.

Well, I think so too. I made a wrong judgment at first, thinking it was a problem with LSS judgment. Thanks to everyone above.

Can't you just remove those six zeros?

The numerical range that batch processing can directly handle is -2147483648 to 2147483647.

Regarding large number processing, the p processing can still be solved; another way is needed; refer to:

Respectively, addition and division of large numbers are carried out, and the ideas for multiplication and subtraction are similar.. Study by yourself..

Wow, thank you, moderator. Just discovered this forum, didn't expect such quick replies～～

About the numerical comparison commands in batch processing, like lss, equ, etc. Can you give me a detailed explanation?
