It is possible to save a value of \fBcur_term\fP for subsequent
use as a parameter to \fBset_term\fP, for switching between screens.
Alternatively, one can save the return value from \fBnewterm\fP
-or \fBsetupterm\fP to reuse in \fBset_term\fP.

.SS Terminfo Names
The \fB@TIC@\fP(1) and \fB@INFOCMP@\fP(1) programs use lookup tables for
the long and short names of terminfo capabilities,
\fBstrcodes\fP.

.SS Terminal Type
+A terminal description begins with one or more terminal names
+separated by \*(``|\*('' (vertical bars).
On initialization of the curses or terminfo interfaces,
-\fBsetupterm\fP copies the terminal name to the array \fBttytype\fP.
+\fBsetupterm\fP(3X) copies the terminal names to the array \fBttytype\fP.

These symbols provide a faster method of accessing terminfo capabilities
than using \fBtigetstr\fR(3X), etc.

+The actual definition of \fBCUR\fP depends upon the implementation,
+but each terminfo library provides these long names defined to point
+into the current terminal description loaded into memory.
