Hello,

I currently have an array which contains several strings. I cannot figure out how to loop through each element of the array and output them on the status window. I tried the #FORALL command but it didn't seem to work. Anyone able to offer a suggestion?

Thanks

#forall @array {#say %i}

When you want to access each element in something like a #FORALL, you use %i. Nested loops of any kind use the next available letter down to like %z minus already-used combinations (for example, you cannot use %t or %x because they are reserved for the %1...%99 system variables (%x10, %t2, etc)).

Instead of %replace (which works) you can also use the built in function designed for this, %expandlist(@array, %cr) .

Edit: I should add, the advantage of %expandlist, besides setting you up for %expanddb when you need it, is that it only expands the main/outside list--if you have nested lists or a string containing the pipe character, it'll show that nicely... an example:

#show %expandlist("(A|B|C)|2|3",%crlf)

vs.

#show %replace("(A|B|C)|2|3","|",%crlf)

Maybe im setting up my array incorrectly. I capture some text that looks like this :

Did you try expandlist?

#show %expandlist(@statusarray,%crlf)

I am just guessing that there is something wonky with your list, for one thing you should be using %concat() to string it all together.

However, there's also A Better Way to do what you're doing. You can use a variable (db var nested inside a list, probably) to store just the information, and then use an alias to display it nicely formatted, instead of storing the formating with the data. I'll have an example in a bit.....

#show %expandlist(@statusarray,%crlf)

Also outputs the word Array. Its wierd tho, if i copy the contents of the list into another variable, called testarray both methods of output work fine...

Er. Do you have a variable called status? If so, that's the problem.... and you can probably use @{statusarray} to work around it.

Edit: Or an input trigger which #gags when you send status!

However, here's the Better Method I was talking about:

wow that works pretty good

I put a #gag at the bottom of the RDMP trigger and it keeps flashing the rdmp output and then gagging it which is rather anoying i have never seen this before??

also how do i output the showparty on the status window now? if i output the party variable with expandlist it works great but with no formatting

if i remove the for loop in the trigger the gag works fine... but i can't find anything wrong with the loop...

Oops, status window, right... Mmm. Yeah. I totally forgot about that, you're possibly going to have to go back to some variation on your original way because I can't think of any simpler way (meh).

About the gag, it is possibly just a little lag in the for loop, try putting the gag above everything else (should have no impact on that script).

I'll keep thinking about it but my latest brilliant idea crashed ZMud (annoying) and I need to run off and do some other stuff for a while, too.
