I want to send the result of executing .EXE as a string into a batch file and use it as a variable in the batch. How to achieve this? Thanks!

If you can describe the problem more clearly, I think your problem will be much easier to solve.

I now want to make the result of EXE running not return in the form of 0 or 1, but return a string, assign this string to a variable in the batch file, and compare it with the existing string in the batch file to see if the output characters are correct. How to implement it?

Yeah! I also want to know! Please teach! !

The result returned by an EXE file is not determined by your subjective wishes, but by the EXE file itself. You can use the errorlevel environment variable to judge the result returned by the EXE file. Of course, your batch processing can judge what situation the EXE file encountered during execution according to the value of errorlevel and display it.

By the way! Can we change to another solution! That is, write the required string into a file in the exe, and then the batch script reads the content of that file and assigns it to a variable for comparison?

It can be achieved with setinfo.exe

Re windrate: This is certainly possible, provided that you can modify this program, whether it's modifying the source code or disassembling it. Additionally, outputting the program results to the system environment variables seems to be an old topic, and many solutions have emerged, but generally, it's to first generate a string similar to "set var=string" and then execute it as a command. Under moderate restrictive conditions (command extensions and third-party programs not allowed), you can use debug to generate a string prefix file, then append the program output to this file, and finally run it as a batch program. Under the highest restrictive conditions (command extensions and external commands not allowed), you can use a pre-edited string prefix file. Of course, you can also use the specific output of other specific commands (which may be internal or external commands), which is more complicated.

Is this EXE you wrote yourself? If so, you can take a look at this, which explains this method: http://www.doshome.com/bbs/dispbbs.asp?boardID=5&ID=7288

What the 3rd said is right. The redirection function means: your EXE program > result file name.

If there is a return code (errorlevel), it's easy. Please see:
if errorlevel 1 set el=you are right
if errorlevel 2 set el=you are wrong
if %el%==you are right goto XXX
if %el%==you are wrong goto YYY

The key commands used are: > redirect to file, strings or inifile read strings. For the specific method, please refer to the help yourself.

If you must follow your idea, 4DOS can help you achieve it. It has a screen reading function, and then you can directly assign the read content to a variable. Of course, if you want to use this as a judgment condition for execution, you must know all possible execution results of the.EXE
