Most of the <EM>extensions</EM> in this fixed repertoire were additions to the

+ tables of Boolean, numeric and string capabilities. Rather than change
the meaning of an existing capability, a new name was added. The
terminfo database uses a binary format; binary compatibility was
ensured by using a header which gave the number of items in the tables
terminfo database may have other extensions, <EM>ncurses</EM> makes explicit
checks for these:
- AX <EM>boolean</EM>, asserts that the terminal interprets SGR 39 and SGR 49
+ AX <EM>Boolean</EM>, asserts that the terminal interprets SGR 39 and SGR 49
by resetting the foreground and background color, respectively,
to the default.
The command "<STRONG>tput</STRONG> <STRONG>clear</STRONG>" does the same thing.

<EM>ncurses</EM> capabilities in user6 through user9 (u6, u7, u8 and u9)
which tell how to query the terminal's cursor position and its
device attributes.
