3/* This file contains functions which simulate the termcap functions.
4 *
5 * It doesn't access a "termcap" file. Instead, it uses an initialized array
6 * of strings to store the entries. Any string that doesn't start with a ':'
7 * is taken to be the name of a type of terminal. Any string that does start
8 * with a ':' is interpretted as the list of fields describing all of the
9 * terminal types that precede it.
10 *
11 * Note: since these are C strings, you can't use special sequences like
12 * ^M or \E in the fields; your C compiler won't understand them. Also,
13 * at run time there is no way to tell the difference between ':' and '\072'
14 * so I sure hope your terminal definition doesn't require a ':' character.
15 *
16 * getenv(TERM) on VMS checks the SET TERM device setting. To implement
17 * non-standard terminals set the logical ELVIS_TERM in VMS. (jdc)
18 *
19 * Other possible terminal types are...
20 * TERM_WYSE925 - "wyse925", a Wyse 50 terminal emulating Televideo 925
21 * ... or you could set $TERMCAP to the terminal's description string, which
22 * $TERM set up to match it.
23 *
24 * Note that you can include several terminal types at the same time. Elvis
25 * chooses which entry to use at runtime, based primarily on the value of $TERM.
