1st question, the readme says,
CONVERSATIONS
If no gotos are specified the conversation will be displayed progressing
in a linear fashion. You can think of a conversation as sort of a
very rudimentary BASIC program.
To goto a line and perform its actions but not display its text, enter
the negative of the line number in the "goto" field.
CONSTANTS
<arg>: argument specified in line action dialog
If conditions
-------------
1: true if player has <arg> coins or more
2: true if player has item of type <arg>
4: true if flag # <arg> is set
5: true if player permflag # <arg> is set to <arg2>
Action conditions
-----------------
1: remove <arg> coins
2: give player item of type <arg> <arg2: how many>
(1: silver key, 2: gold key, 3: plat key, 4: magic potion, 5: health potion)
3: remove item of type <arg>
4: set permanent flag # <arg>
5: set player permflag # <arg> to <arg2>
(1, 2, or 3)
8: permanently validate sprite <arg> on level <arg2>
9: destroy this sprite permanently
2nd question, I don't know, look in ResEdit,
3rd question, I don't know, from what you told me before, you seem to be doing everything right
------------------
Stupidity got us into this mess, why can't it get us out, too.
