The first thing I did was add a few new global variables, and modify others:
- optN, optNsize
- (new) This is the number of counters, and the number of digits required to represent the number of counters.
- attr_gif, attr_txt
- (modified) These are two attributes structures, one for GIF-encoded files and one for text files.
I've modified them to be arrays rather than scalars.
- attr
- (new) This is the attributes structure for the directory itself.
You'll notice that the attributes structures and the OCB remain the same as before; no changes are required there.
