China DOS Union

Question for the experts: for the DOS batch file below, how should the program be written?
1. There are many TXT files named with numbers (from small to large). Now I need to change all those numeric filenames as required (for example: add 100 to all of them), still keeping them in ascending order.
2. Take the renamed TXT files and, at a specified time interval (such as 10 seconds), copy them one by one in ascending order
automatically to another place (such as C:\...TXT-----G:\...TXT)

The above is a major problem I have run into recently, I kneel and beg the experts to tell me

First say what your runtime environment is.
Also, what are the starting and ending values of your numbers?
If it is a system 2K or above, and the starting value is 1 and the ending value is 100, then it can be like this:
for /l %%a in (1,1,100) do ren %%a.txt %%a100.txt
for /l %%b in (1,1,100) do wait 10000 && copy %%a100.txt g:

I didn't quite understand your question. Do you want to add 100 to the numeric value, or add the characters 100 before or after the filename? You'd better give some examples of the filenames and what they become after renaming. Are these filenames consecutive? If they are numbers, then naturally there are smaller and larger ones, so what is the range?

Hello: the numeric filenames are all 14 digits long... for example 11112222333333.TXT..... add 100 from small to large
There are 58 TXT files in total...... waiting again for your reply, thanks

To be honest-------your second explanation is even more confusing than the first one.

Re kumho:

Your description of the problem really is somewhat vague and unclear. For example: you did not mention what system environment you are using, whether your filenames are consecutive numbers, and whether adding 100 is in the mathematical sense or the textual sense.

If you are using it under cmd, then it will not be very complicated; if under DOS, then some special handling is needed, but that only applies to the specific application, so you need to describe it as completely and clearly as possible.
