arithmetic batch file

I need to create a batch file which will input numerical data from a file and perorm some mathematical operations, then send it to another file. I am new at batch files and have not found anything to do with arithmetic manipulation of data. If anyone can help, thanks a bunch.

Batch files, in dos, are pretty limited. There are two approachs people have used. One is to create text stacks and push and pot things from them. The second is to actually write a little assembler program to handle the job. I think you can find some of these at PCmag's web cite.
