Ok, I've got an extremely old version of DOS that needs to launch a batch file that requires cmd.exe . For this reason there are two things I can't do. I cannot simply launch the batch file by entering in the path\filename and i can't use "start Path\filename" because start is a relatively new addition to the DOS. So what I'm looking for is something I can type into an OLD version of dos that will call up the CURRENT CMD command prompt, execute the batch file, and then close. So far... I'm lost.
