BATCH script to save DATE to a variable (Users)

Thank you!
That's so obvious, how didn't I notice it?

Thanks for this!

I mainly use DOS 7.1 and 6.22 with the standard shell. I use FreeDOS too but not for this.

There's a freeware diagnostics program, NSSI, that I run on different computers while testing them, that is hard coded to print an error message if the current date is past 2008.

So with my script I save the current date, set the date as 12-31-2008, run the program, and then set the correct date again.

Using assembly is probably a better way to do this, I agree. But it's out of my capabilities (at least for now). So your code is nothing short of black magic for me.

I compiled it and it prints the date this way:
Sat Mar 01,2025

But it doesn't create the DATE_ variable.

Could you please tweak your code so that it saves its content to the variable DATE_ with the date in this format MM-DD-YYYY? That's the format I need to use in my script to set the current date with the DATE command.

Is it possible to create/set a variable (the same way the SET command does) with an assembly program? Could you please give an example of assembly code that sets this environmental variable FOO=BAR? Just to try to understand it better.

If you can recommend any reading material on assembly for beginners that'd be great.
