Is there a way when a trigger executes to read the first line that it triggered on then increment to the next line? I get a list of stuff and I can grab the first in the list but not sure how to grab the rest, it would be nice if I could increment until I hit the end which would have another trigger closing out the list.

I get something like this:

/---------------------
| Store Item
| Acme Apple
| Walmart Pear
| Best Buy Speakers
\---------------------

So in the above when I see "| Store" I grab the next line and load Acme and Apple into my database, then I keep incrementing and loading till I get to "\----" then close it out.

Thanks!

EG.,

#trigger {/---} {#T+ grabdata}
#addkey database %1 %2
#trigger {\---} {#T- grabdata}

You have a class that contains the pattern(s) for storing the data which enables/disables when you want it.
#trigger {pattern} {
#addkey dbvar store item
}

There is really no 'increment' you just grab each required pattern until you reach a non-matching pattern. HOWEVER, if you have multiple stores with same name (key) then any match after the first will overwrite the first. In which case you would need a unique key and that would mean your key=value 'pair' is now a nested

key="key=value"

In theory you could put the ending pattern into the starting pattern by use of a TEMP trigger but I remain unconvinced that they are totally stable. As in:

#trigger {/---} {
#TEMP endgrab {\---} {#T- grabdata}
#T+ grabdata
}

Hmmm thanks but sadly I don't think this will work. :-/ My problem is it's not as clear cut that a pattern will do it or I would. I have stuff like this:

/----------------------
| Store Item
| Acme Apple
| Pear
| Orange
| Giant Grapefruit
| Banana
\------------------------

So it's not repeating the Store every row like you would say see in Excel, thus my need for a way to increment.
I think I've found a solution with %line, it's going to be a pain but it should work. When I hit the end (which I CAN find out lol) I'll do %line(i) where i starts as 1 and increments until I reach "| Store" then use the resulting value from i to step through the list.
This way if I see Acme as the Store and then a blank in the next row I know that the Store is still Acme and can associate Pear with Acme. Not a GREAT solution but it should work.

P.S. the values above are spaced in the game so the Store always starts in Col 3, Item in Col 90, etc.

You want a stated trigger.

Thanks shalimar, this works!

Now I am struggling MIGHTLY with the limited functions available to me. Like I know the position of each column but since there appears to be no Mid Function in CMUD I think I need to basically write my own. :-(

%len(string)/2 will give you a mid point for odd number of chars and an approximate for even length. You can try

#IF (%mod(%len(string),2)=0)

in a function, which should test for even length or odd.

Hello, thank you very much, I also needed it and I did as a colleague above wrote to set the trigger to 0 thank you very much I looked everywhere and unfortunately I could not find it, but here I finally found on this forum, for sure it will be useful to other people
