- If only it were so!
-
- There are eight color sets, numbered zero through seven. Each
- character on the screen is associated with exactly one color set.
- Now, you can have any foreground and any background you like assigned
- to a given color set -- but there are only eight sets, so you are
- limited to a total of eight color combinations displayed at once.
-
- (On the other hand, you can specify fractional red, green and blue
- values for each color set. As a co-worker of mine observed: "You can
- only have eight colors -- but they're eight _bitchin'_ colors.")
-
- Worse, hpterm remembers where you specified that a color should begin
- to be displayed. The only way to be sure that you're getting a clean
- slate of colors is to use the clear-to-end-of-line command ("nuke it
- from orbit") and redraw the whole line.
-
- As if that weren't enough: since my original article I've found out
- that only eight of the twelve function keys generate distinct escape
- sequences -- F9-F12 repeat F1-F4 -- and the arrow keys can't generate
- escape sequences at all!
-
- I hate hpterm.
