Defines the terminfo terminal capabilities database.
On UNIX™ platforms, the TERMINFO environment variable points to the terminal capabilities database. This variable must be used in conjunction with TERM, when INFORMIXTERM is set to terminfo.
You should not have to modify or set this environment variable. The default is defined by the UNIX system, it can be for example /etc/terminfo, /usr/lib/terminfo, or /lib/terminfo.
It is important to define terminal capabilities properly according to the text terminal hardware or the terminal emulation you are using. In particular, function keys (F1, F16) and display attributes (bold, reverse, colors) may not work if the escape sequences do not correspond to the terminal used.
For more details about the TERMINFO environment variable, please refer to your UNIX operating system manual.
