unfortunately, it seems that most of the precious findings previous modmakers have made about npc scripting are more or less lost.
there's a big gap resulting from all good scripters dropping out at some time without passing on the info, which means that everybody who wants to script has to reinvent the wheel.
yet this is dramatic becasue the scripts are the heart of ja2's story and npc interaction, key to the cut scenes, the characters to hire and sometimes the script even has further infuence on the behaviour of characters than we'd think.
I can't write a tutorial or walkthrough for scripting because it is very difficult to put it inot words abstractly, also, depending on what npc scripting programme we use, things look different anyway
so what i'm going to post is merely dropping some info to the forum in order for smart enough people to figure it. It is quite more demanding than other aspects of modmaking, so one should brace himself with a high frustration tolerance and a lot of patience and some serous abstract logical thinking capabilities.
Plus, i don't know much about it myself, so the more i write, the higher the chance i tell you guys something wrong.
there are a few programms, npc edit, npc.exe. some betas, the npc scripter (russian)
but of course they edit the same type of file so what they do in the end is the same, just the GUI differs.
in any case, the npc script is an assembly of single records.
records may differ according to if they're used at all, only once a dialogue, only on certain days... etc.
Records are ONE BIG "IF X ---> THEN Y" logical condition, split into an input/ conditions part and an ouput/ actions part
the different GUI's might show it differently.
let's look at general aspects that apply both to input and output first:
every progamme will have an entry whether or not the record in question is USED at all, or whether it is not used, used at specific days
every record has a byte that defines whether used just once, used once a record or used always.
while this is important, it is pretty self explanatory, depending on the programme, you'll have to find the right byte if it isn't labeled.
Some records might have to be at a special place inside the script in order to work: One example is when an RPC is being recruited for money after a yes/ no popup, the record where he joins seems to only work as record 1
also, not every record can just be shifted around inside the script. Some records are activated by hardcoded routines, one example is carlos. His record 1 is activated upon the player being beamed to the basement (see later the list of NPC actions)
Also, pop-ups, and especially the reaction to pop-ups are rather restrictive in this sense, they shoudl be left in place if you want to use them. it is rather difficult to activate popups beyond copy-pasting the entire script.
let's have a look at what the two parts of the scripts do
the input side:
several input conditions must be met to activate the output:
1. player/npc interaction
*edit* credits for all listings go to trailblazer, neyros and realist
[PCInput]
//--------------------------
1;Friendly approach
2;Direct approach
3;Threaten approach
4;Merc tries to recruit NPC
5;Repeat approach
6;NPC receives an item
7;NPC initiating conversation
8;NPC initial quote
9;NPC who are you
10;This record was triggered by another record or NPC
11;Approach giving first aid
12;Approach with special initial quote
13;Approach Enemy NPC quote
14;Approach declaration of hostility
15;Escorted PC in wrong sector
16;Escorted PC is recruited
17;Approach with initial quote
18;Shop is closing
19;Current sector is not safe
20;Finished slapping
21;Finished Punch_0
22;Finished Punch_1
23;Finished Punch_2
24;Finished opening object
25;Finished getting an item
26;Finished giving an item
27;Finished traversal
28;Approach to Buy/Sell
29;Friendly/Direct/Threaten/Recruit
30;Friendly/Direct/Recruit
[End]
these entries define at what kind of interaction the record is used. Some of these interactions are player-initiated, others are defined in other records of the npc's own script, such as 10 or 24-27
2. Leadership check
some interactions can be coupled with a check for leadership
note that the number given in the script is modified by the merc in question and the npc in question (see prof.dat) and might not always work ingame.
a leadership check only makes sense if a player-initiated input is used, obviously.
3. Active quests
[Quests]
//--------------
0;Deliver Letter
1;Food Route
2;Terrorists
3;Kingpin Chalice
4;Kingpin Money
5;Runaway Joey
6;Rescue Maria
7;Chitzena Chalice
8;Held in Alma
9;Interogation
10;Hillbilly Problem
11;Find Scientist
12;Deliver Video Camera
13;Blood Cats
14;Find Hermit
15;Creatures
16;Find Chopper Pilot
17;Escort SkyRider
18;Free Dynamo
19;Escort Tourists
20;Doreen
21;Leather Shop Dream
22;Escort Shank
23;[UB] Destory Missiles
24;[UB] Fix Laptop
25;[UB] Kill Bloodcats at Bettys
26;[UB] Find Musket For Raul
27;No 27 Yet
28;No 28 Yet
29;No 29 Yet
[End]
In the input side of the record in question, you may check for active quests. This has a similar effect as the global activation checks, if that quest isn't active, the record won't be used.
This on/ off switch can be used very nicely to have Questgiver NPC's behave different once their quests are finished. a typcial example in vanilla ja2 is auntie

3. Item in the inventory of the NPC (Npc gets item, npc has item)
the input side may also check for an item in the possession of the NPC. This is especially important to prevent a crash that happens when an NPC tries to give an item he in fact doesn't have
it is also used in conjunction with the player input "npc receives an item" in pretty much any item-related quest
The game can use numbers beyond 350 for this purpose, so you can use 1.13's items.xml entries too
in one of the GUI's, this part is coupled to the next section, check for Grid
4. Npc stands on a grid
This check not only allows for an on/ off switch like previous checks, it also allows to script movement. Characters can move to specific places in the sector where they can do other actions. One example is fatima who walks over grids defined in her script. This part of the input script can check whether an NPC has reached the grid in question and then continue the path or the action.

Output side
The output side contains an NPC's action and speech, but also a big number fo sometimes very important actions. Many of those are not restriced to the npc in question but affect the Merc doing the talking, the overall game itself or other Global aspects.
1. Npc Speech
If the conditions on the input side are met, the NPC speaks his lines as defined in the output side. This is crucial for telling any story that might make sense.
Another important function of speech is that it is sometimes necessary for a script to continue. There sometimes are actions that won't work without speech, for example you can't jump to an NPC and away from that NPC again without some sort of action or speech.
however, these are special cases, but whenever a record isn't activated despite all conditions of the input side being met, it's worth a try to add some speech 
2. NPC actions

4. Npc gives an item
This is the counterpart to npc has an item and or npc gets an item. See above, npc's should only give items if they also have it, otherwise you risk crashes.
5. Quest given/ activated
the output side my also activate quests and add entries to the history log while doing so.
for a list of quest, see above my comments on the input side
6. Quest closed
this closes the quest, adding a black entry to the history log and turning the other, formerly red entry, black too.
7. Jump/ Activate other scripts/ records
This one is particuliarly important for any storytelling beyond simplictiy. It is (one of) the counterpart of player interaction 10 (record was activated by other record or npc) of the input side.
By entering the npc number to jump to and the record in the script of this NPC to which you want to jump you can activate a different npc's and sometimes also EPC's npc script without any more player interaction. However, a jump may sometimes also cancel an NPC action or movement or such, so place them wisely in the script.
note that there are specialities in the cut scene scripts where deidranna/ elliot/ joe jump to each other.
8. Move to grid
This is the output counterpart of "npc stands on grid"
it makes npc walk to the grid specified if they can reach it (pathfinding, locked doors with the npc not having "key" box checked in the map file, etc)
see the additional posting below for means to modify movement from grid to grid
9. Stopwatch
if ever you encounter these numbers
-536 Stopwatch -535 Stopwatch off
it means that the player can't do anything during the stopwatch. This can be used to prevent exploits like shooting questgivers after doing their quests or simply to prevent the player from interfering into a difficult scripted action.
there ae a couple of more entries that i don't know or that are always 0 or that i forgot.
i will be updating these posts if get around to, and hopefully fix mistakes and give credit
most of the lines were probably first dug out by trailblazer, then neyros and the makers of the npc scripter deserve credit too.
if somebody would be so nice to translate the gibbersih entries to russian and from russian to english, that'd be nice too.
The different entries match more or less to the list of triggers and npc actions in the code, credits to realist for digging them out.

addition:
not all NPC actions can be done by all bodytypes.
If an action doesn't work despite all conditions being met, try assigning a fighting bodytpye (e.g. reg male, reg female) to the character in question using proedit
addition:
some npc actions (e.g. action 8, running, or action 3 opening closest door, or action 150 teleporting) are used in conjunction with movement (see earlier the explanations on movement)
teleporting needs no path from one grid to the other.
the activation of these actions may slightly differ from script to script and according to which programme you use.
addition:
Dual-use scripts:
The scripts 160-196 are used for deidranna-elliot cut scenes:
Elliot Record Deidranna Record
Event: Omerta 180 160
Event: Drassen 181 161 15
Event: Cambria 182 162
Event: Alma 183 163
Event: Grumm 184 164
Event: Chitzena 185 165
Event: NW sam site 186 166
Event: NE sam site 187 167
Event: Central sam site 188 168 57
Event: Sent Flowers 189 169
Event: Won back a town 190 170 70
Event: Interrogation 191 171 73
Event: lose support scifi 192 172 101
Event: Skyrider 193 173 109
Event: Madlab Quest 194 174 113
Event: approach meduna 195 175
Event: Balime 196 176
however, current prof.dat's go up to slot 169. (Mods like Demise of Man may have even more slots, but demise of man also has the possibility to use "alternate npc scripts" so these slots don't conflict in DoM)
This means, for example, that your script for character 163's npc interaction is the same script that is used for deidranna during the "alma" cut scene. So you're not supposed to carelessly overwrite it in order to change slot 163's behaviour. Rather "add" your records for slot 163 after the records needed for the cut scene. According to my observations, these records ARE used and not, as we coudl suspect, be ignored.
Remark to this example: slot 163 might be used for vehicles or other "invisible" profiles. Handle with care times two...

@ sincleanser
1. Most characters have such scripts by default in npcdata.slf. so you don't have to add any new scripts for most characters to work and certainly not for the game as such to run.
if you add a character on slot 65 or 71 for example, where thre's no script already in place, then you just can't interact with them if they don't have a script. Some slots share their script with cutscenes though. i think i should add that to my above postings.
Btw the .npc scripts don't cover all aspects of noc dialogue, e.g. some comments are "standard" without mention in the scripts. But even these "standards" seem to only exist for default used character slots, e.g. not slot 65 or 71.
2. "Completely changeable" would require a lot. See, for most npc actions to function, there needs to be hardcoded npc action. the scripts only activate these actions, if the exe doesn't have code for them, the scripts won't have any effect. Fo example the "sex with npc" script doesn't work in that censored version of ja2 where the "sex" animation is disabled.
In order to change these scripts within the realms of currently existing triggers and code, you don't need to change the format or anything, often, simply replacing one value with another does the job.
However, in order to move beyond the limits of current npc actions and triggers, it is most likely that a move to .lua would be the most beneficial thing to do and also the most innovative thing for story modding to ever happen. That said, the idea that scripting will become easy just because we'd use luad instead of .npc is an illusion. The subject matter as such is hard and complicated and i don't know if even the mighty lua can make this matter accesible enough for easy editing.
@Khor
Advancements in the scripting engine would be the very requirement for non-hardcoded new events of all sorts. That would be nothing short of a quantum leap. There are a few coders that work with .lua and they do great things, let's hope the npc scripting at some point is possible for them to tackle. Whether a complete rewrite is possible, or if .lua would allow to simply add new, custom npcactions that can be triggered with npc scripts, both would open the doors very wide for future modders to achieve custom stories and events.
For example translating the existing "facts" from hardcode to external lua would allow to majorly redesign many quests and add flexibility where we, as of today, have to work around the hard code.
