- I don't deny that there are some cases where there's a difference. But
- how often do you really have problems with complex macros? If it's as
- often as once a week, I'd suggest that you're doing something wrong.

- Under DOS, nobody is sharing the CPU with you. Under DOS, the weird idea
- that you should pass a manual page through a text formatter every time you
- want to look at it never caught on; help systems keep their text in a format
- that's convenient to display.

-
- Under DOS, there are lots of programs available to search the text contained
- in archives without uncompressing them, and every archive program that I've
- ever seen will list the filenames without uncompressing the archive. For
- example, I'd probably run
-
- pkunzip -v huge foo*.c
-
- to do what you did above. The idea that you have to uncompress
- anything at all just to see the filenames strikes me as a very bad design.
