Forums Scripts & Popups "var $+($chr(37),$readini(blah)) = 0" eval problem

Ok, basicly iv got a loop that creates vars along with doing other things. It needs to create the var names from reading a ini file.

Basicly at the end of the loop it might have 10 temp var's with the names all coming from ini "items".

Now i have a problem doing this, for reading the var it works fine like..

What happends is in the end result, like in a msg or something, it returns the value of the variable. No biggie right?

But when i use that for /var it does not like it. Im sure since it works like i posted for every other use im using it in, that im evaling it a wrong amount. But what would the right amount be? i tried 1 and 2 sets, and no sets of eval brackets. But what am i doing wrong? Here is more facts if you will.. Keep in mind im not posting from my comp so i cant copy paste the code.

Basicly i want to make a variable with the name "%valuesname" as shown in the example of an ini file below.
Blah.ini
[GroupName]
ItemName=ValuesName


what iv done to read this variable is "[ [$+($chr(37),$readini(blah.ini,GroupName,ItemName)) ] ]" and that works fine.

But i cant make /var make that variable. How do i do this? Thanks and sorry for my ramblin, im doin a buncha dif things at once lol. So forgive any miscommunication plz :tongue:

I am not sure if I undertood your issue correctly. Are you using the /var command in a script? Or is it in a command line? If it is from a command line (the editbox where you write your chat text), you should try using //var - this will first evaluate all the variable and identifiers for then set the temporary variable.

If that is not what your problem is, sorry, I misunderstood it :P

Zyzzyx

var % $+ [ $readini(blah) ] = whatever

"var % $+ [ $readini(blah) ] = blah"

Does NOT work, heck even if i use the variable sign "%" it says the readini is invalid. however if i change % to $chr(37) it atleast does not show an error. It just does not work as intented, the var command does not make the correct variable.

but as i said even with "$chr(37) $+ [ $readini(Blah) ] = blah" it does not work.

Im getting very stummped as to why this is not working. i can get it to read the var being created no prob but getting it to make a "var" persay is not working. What is happening in the loop is that its not being made with the /var command and instead being made by the "inc" command via the part i posted above. and by doing so it is creating a none temp variable. just like the set command does. Here is an example of my code below. It is trying to list a ini files groups basicly, and organize the groups. Sorry this wasent posted befor but im starting to think its needed so i trasnfered it from my comp via floppy magic! :tongue:




keep in mind the msg Zeus junk is just for testing reasons, and i know theres a var command behind a comment. I didnt wanna delete it atm :tongue:.

Anyway plz help this tiny thing is driving me nuts!!


(Btw any coding improvement notes are happily accepted

var [ [ $+($chr(37),$readini(Dat\Items.dat,$ini(Dat\Items.dat,%x),Type)) ] ]

if the value in your items.dat = "test", then your var statement is [ %test ], which would probably be $NULL

change it to:

var [ $+($chr(37),$readini(Dat\Items.dat,$ini(Dat\Items.dat,%x),Type)) ]

(you are evaluating once too many times)

Remove one surrounding set of [] with your inc statement too

set $+(%,$readini(blah.ini,GroupName,ItemName)) value_of_the_string

mIRC seems to have a problem with attaching variables/identifiers to other parts of a variable name in /var declarations, you can see this with simply:

//var -s % $+ $me = test

The value becomes "= test" instead of the expected "test". You could remove the = of course but this leads to problems when using identifiers with a variable as a second or onwards parameter:

//var -s %i = 1 , % $+ $me $gettok(string,%i,32)

As you can see you get an invalid format error, because the variable preceeded by a comma confuses mIRC since this is the method used to declare multiple local variables. The best way to accomplish what you want, so you are able to use a value without any possible errors is to use:

//set -l % $+ $readini(Dat\Items.dat,$ini(Dat\Items.dat,%x),Type) value

Which seems to be exactly what you want. /set -l creates a local variable so it still expires at the end of the process. There's no need to escape the % with $chr(37), you may even join more parts of the variable name with $+() such as $+(%,$readini(...),.,etc.)

Yes!!! Thank you "Sigh"!!

So were dealing with a bug not a coding error? And troyboy i tried only evaling it once like that, it still didnt work. The only way i got it to work is by simply replace the text "var" with "set -l" and WOOHOO IT WORKS.

And i should restate myself, this could not be a bug and more of a "working almost as intended" lol. but its all good, it works and yay! Ty!

set -l is undocumented strangely enough!
I think it's far too usefull to be left out of the help file...

lol really? i got an updated mirc help file so its in mine. I just dont know all the so called problems with /var.

thats the link for the updated help file, i havent needed to use many of the undocumented stuff but none the less its a nice little update. Enjoy

I found that I had run into this problem 2 years ago (mirc 5.91) when I scripted my TBserv file sharing script.
my code was:


And it still works in mirc 6.16.

As for "set -l", where is the updated documentation?
I couldnt find it in the link from the previous post.

I explained why it was important to be able to include the = sign:



Of course with /set that = sign isn't needed which is why /set -l is better to declare local variables of this nature. But if you stick to your method you don't even need evaluation brackets, //var %namecount $+ %count 1 is fine
