+ * MAIN PROGRAM
*
- * If the current loc is zero, it means the clown got himself killed. We'll
- * allow this maxdie times. MAXDIE is automatically set based on the number of
- * snide messages available. Each death results in a message (81, 83, etc.)
- * which offers reincarnation; if accepted, this results in message 82, 84,
- * etc. The last time, if he wants another chance, he gets a snide remark as
- * we exit. When reincarnated, all objects being carried get dropped at game.oldlc2
- * (presumably the last place prior to being killed) without change of props.
- * the loop runs backwards to assure that the bird is dropped before the cage.
- * (this kluge could be changed once we're sure all references to bird and cage
- * are done by keywords.) The lamp is a special case (it wouldn't do to leave
- * it in the cave). It is turned off and left outside the building (only if he
- * was carrying it, of course). He himself is left inside the building (and
- * heaven help him if he tries to xyzzy back into the cave without the lamp!).
- * game.oldloc is zapped so he can't just "retreat". */

- * him to try to get out. If he doesn't within clock2 turns, we close the
- * cave; if he does try, we assume he panics, and give him a few additional
- * turns to get frantic before we close. When clock2 hits zero, we branch to
- * 11000 to transport him into the final puzzle. Note that the puzzle depends
- * upon all sorts of random things. For instance, there must be no water or
- * oil, since there are beanstalks which we don't want to be able to water,
- * since the code can't handle it. Also, we can have no keys, since there is a

- * from now until clock2 runs out, he cannot unlock the grate, move to any
- * location outside the cave, or create the bridge. Nor can he be
- * resurrected if he dies. Note that the snake is already gone, since he got
- * to the treasure accessible only via the hall of the mountain king. Also, he's
- * been in giant room (to get eggs), so we can refer to it. Also also, he's
