The DOS I learned was DOS 3.1 back when I was in school, so I don't know it very well. I downloaded a batch file guide from the forum, and I was very interested in this FOR command line: "for /f %a in (TODEL.txt) do del %a". But when I tried it, the system reported "syntax error". for /f %%a in (kivifi.txt) do del %%a for /f %a in (c:\kivifi.txt) do del %a for /f %%a in (c:\kivifi.txt) do del %%a All three commands above give a "syntax error". I don't know where the problem is. Please give me some pointers, experts. Thanks!

What is the runtime environment?

MS-DOS 7.1, with IFS loaded, supporting NTFS read/write. I want to make a small program to delete viruses under DOS.

Thanks everyone for the support. Looks like I'll have to think of some other way.
