The next two variables are our running total of the number of disks we've used so far, and how many bytes we've used on the last disk. The for command iterates over all the files in the current directory. For each one, we call :onefile with the file name. The :onefile subroutine does all the real work.

It then sees if that size is larger than a floppy disk; if so, then we're doomed, so we just skip the file. Otherwise, we add the file to the current disk and see if it fits. If not, then we declare the disk full and put the file on a brand new disk. This algorithm erroneously reports that no files require one disk.

Fixing that is left as an exercise. There's your quick introduction to the secret :eof label and batch file subroutines. Comments are closed.

You could create separate :labels for different errors, and have each return a unique error level. All in all i would recommend using exit just because you can set an errorlevel, but, it's really up to you. Stack Overflow for Teams — Collaborate and share knowledge with a private group.
