What is the best character to use as a delimiter in a custom batch syntax?

Question

I've written a little program to download images to different folders from the web. I want to create a quick and dirty batch file syntax and was wondering what the best delimiter would be for the different variables.

The variables might include urls, folder paths, filenames and some custom messages.

So are there any characters that cannot be used for the first three? That would be the obvious choice to use as a delimiter. How about the good old comma?

Thanks!

Answer 1

You can use either:

1. A Control character: Control characters don't appear in files. Tab (\t) is probably the best choice here.
2. Some combination of characters which is unlikely to occur in your files. For e.g. #s# etc.

Tab is the generally preferred choice though.
