Is there any tool to add arithmetic functions to *TRUE* MS-DOS?

I wasn't sure where to post this...

Is there any freeware program/tool that will add arithmetic functions to batch files under true MS-DOS?

In a Windows batch file you can use the SET command to perform basic arithmetic, but that doesn't work under MS-DOS.

I've Googled and although I found a command line program for MS-DOS (EVAL.EXE) that seems like it would do what I want, but naturally the instructions have exactly zero examples of its usage and so far I haven't been able to figure out how to make it work properly with variables.

All the other command line calculators I found just print the result to the screen.

It doesn't help that apparently the command line in Windows is considered MS-DOS, guaranteeing that the majority of the pages that claim to have "MS-DOS" information are really talking about the command line in Windows.

I'm looking for something that will work in true MS-DOS mode, not Windows.

I want it to add some functions to a batch file that will be run in DOSBox. I could accomplish what I want to do by using IF statements and manually setting the variable values myself, but I was hoping to find a more elegant solution.

A user on another forum had the answer for me, XSET;

http://xset.tripod.com/

It has even more features than the Windows SET command and has an MS-DOS version.
