Limits

+       ncurses stores compiled terminal descriptions in three related formats,
+       described in the sections
+
+       o   LEGACY STORAGE FORMAT, and
+
+       o   EXTENDED STORAGE FORMAT, and
+
+       o   EXTENDED NUMBER FORMAT.
+
+       The  legacy storage format and the extended number format differ by the
+       types of numeric capability which they can store (i.e.,  16-bit  versus
+       32-bit  integers).   The  extended storage format introduced by ncurses
+       5.0 adds data to either of these formats.
+
+       Some limitations apply:
+
+       o   total compiled entries cannot  exceed  4096  bytes  in  the  legacy
+           format.
+
+       o   total  compiled  entries  cannot exceed 32768 bytes in the extended
+           format.
+
+       o   the name field cannot exceed 128 bytes.
+
+       Compiled entries are limited to 32768 bytes because  offsets  into  the
+       strings  table  use  two-byte  integers.   The legacy format could have
+       supported 32768-byte entries, but  was  limited  to  a  virtual  memory
+       page's 4096 bytes.
