How to retrieve and parse current directory?

[jeffnc]

Basically what I'd like to do is retrieve part of the current directory name. For example, if the directory (that the Visual Build Pro .bld file exists in) is

C:\whatever\dir 1234 abcd

what I'd like to get is "1234". So first, I need a way to retrieve the dir name and then I need a way to parse it. Thanks.
