Anybody use decimals for line numbers?

[SMcNeill]

I remember a couple old games which used this as an organization method. Was it Zork? Wizardry? The way it worked was by setting code sections into various number ranges.

Example:

Line 100.000 - 199.999 was character creation.
Line 200.000 - 299.999 was character level up + skill acquire

And so on.
