China DOS Union

I want to use batch processing to complete the following functions, please help

a. Find the specified string "LIZI" in the text. If found, assign the text after the space to %1, %2, %3, %4, %5, %6, %7, %8, %9... until the carriage return character is detected, and exit.
If not found, add a line in this text. The content is a string starting with "LIZI" and add the default values of %1, %2, %3, %4, %5, %6, %7, %8, %9... which is the value of the first line
For example, in AAA.TXT there is
name date1 date2 date3
lizi 001 002 003
Looking for lizi in AAA.TXT, there is %1=001, %2=002, %3=003
Looking for name4 in AAA.TXT, AAA.TXT has no change to
name date1 date2 date3
lizi 001 002 003
name4 date1 date2 date3

b. Perform mathematical operations in batch processing and assign values to variables

Does nobody know?

It seems that debug needs to be used, and the easiest way is to use QB/C

I don't know if the enhanced script tool will work.

If batch processing is not possible,

please ask the expert to help write a program to complete

Where are the experts? Come out and help!, this will be very useful when done

First, let's talk about your idea. Maybe we can try another way to do it.

Regarding issue A, I mainly want to find materials about a certain record under DOS. For example, when using GHOST in an internet café, the username and IP are the same. So as long as I first use a tool to obtain the MAC address, then look up the record about the MAC address, I can get the IP, computer name, etc. This can have a greater role in diskless PXE. Regarding issue B, eval.exe can achieve it, but it doesn't assign a value to the variable. Maybe I didn't use it correctly. Please everyone think of a way.

Re huaqingyuan:

Regarding question A, because I don't know your specific requirements, I only wrote a general framework. If it needs to meet your requirements, some details should be modified.

Regarding question B, the code I provided is a general way to save the command output result as an environment variable. Of course, there are other solutions, but this one is simpler; as for the details of eval.exe, I'm not very clear.

The following appends the source codes of the two. For the complete content, please download the file Open the attachment (I'm using the file upload function for the first time, please forgive me if there is an error)

Thanks

Because I had something to do before and didn't see the post, today I saw it and tried it. There seems to be something wrong with the part of adding records about problem A. Maybe I don't know how to use it. Please, Brother willsort, let me know.

Re:

Sorry, there was a small problem with the source program. It's my fault for not debugging properly. Here is the modified file attached: Open attachment

If there are any other questions, please let me know in time.

Thanks again to willsort, you are indeed a master of batch processing

The modified file can't be downloaded now. Can you just paste it here directly? Thanks.

Re: huaqingyuan:

I have made modifications to the code in the original post. The main points are as follows:

1. In the fourth sentence of :OPAPPEND, an extra space is added after ECHO;
Mainly to pass FIND " %1 ", to avoid mis-matching ABCD and BCD;

2. The reference mark of the variable string is changed from single quotes to double quotes;
The forum seems to handle single quotes in a special way, always displaying them twice, which has no impact on the original code;

3. Some other spelling errors;
