1. %VariableThatDoesNotExist is null.
echo $chan this part triggers
if ($eval($+(%,VariableThatDoesNotExist,$nick),2) != $null) {
blah blah
}
echo $chan this part triggers
else {
echo $chan This part does not trigger.
}
Since it does not triger for the != $null, it should trigger for else { }, right? Rather than using else, I've even used:
if ($eval($+(%,VariableThatDoesNotExist,$nick),2) == $null) {
echo $chan This does not trigger
}
Still same. So how do I get it to work? I put the bottom if statement on top of the top if statement. And then it works. In other words, this part works:
if ($eval($+(%,VariableThatDoesNotExist,$nick),2) == $null) {
blah blah
}
elseif ($eval($+(%,VariableThatDoesNotExist,$nick),2) != $null) {
blah blah
}
In other words, order matters (whether %null != $null or %null == $null). 2. mIRC goes crazy when it comes to variables that does not exist. I have. %seenchans #list,#of,#channels If I have. elseif (($istok(%seenchans,$target,44)) || ($target == $me)) { Will only trigger for %seenchannels. But if I have.. elseif (($istok(%seenchans,$target,44)) || ($target == $me)) && ($istok(%VariableThatDoesNotExist,$target,44)) !ison $target) { It will trigger for all channels. So that's a bummer... And then of course, the flood protection. If I have a paste editor that will paste in N cs, then I will see my flood output at N cs. But if I don't use a flood script and enable flood protection in Alt O, my flood slows down but I don't see it as slowing down, so that's a bummer. A mIRC script should not be better than a default mIRC feature. -Neal.

No, an else/elseif have to be used directly after the if statement. 2.

I have.
%seenchans #list,#of,#channels
If I have.
elseif (($istok(%seenchans,$target,44)) || ($target == $me)) {
Will only trigger for %seenchannels.
But if I have..
elseif (($istok(%seenchans,$target,44)) || ($target == $me)) && ($istok(%VariableThatDoesNotExist,$target,44)) !ison $target) {
It will trigger for all channels. elseif (($istok(%seenchans,$target,44)) || ($target == $me)) { This line is correct, i'm not sure why it's not working for you but : elseif (($istok(%seenchans,$target,44)) || ($target == $me)) && ($istok(%VariableThatDoesNotExist,$target,44)) !ison $target) { This line is wrong in any case because $istok can only return $true or $false, so you trying to do something like //if ($true/$false !ison $target) { } and because of the &&, this will never work

But I don't see why it has no longer follow %seenchans and work for non-seenchans too. -Neal.

So you're saying the /echo got in the way? What do you mean, i don't understand :s ? maybe this will help you : alias syntax {
if (1 != 1) echo -a 1
echo -a ?1
elseif (2 == 2) echo -a 2
else echo -a else 1
;-
if (1 != 1) echo -a 1
elseif (2 != 2) echo -a 2
echo -a ?2
else echo -a else 2
}typing /syntax only echo ?1 and ?2 because each time, the /echo *break* the if-elseif-else statement I don't see any problem with the $istok, just use : if ($istok($+(%seenchans,$chr(44),$me),$target,44)) {

Okay, I'll remove the echo's.
This doesn't work.
if (% != $null) {
do this
}
elseif (% == $null) {
do this
}
1 has to work, right? But none trigger.
This does, though.
if (% == $null)
do this
}
else {
do this
}
In other words, I had to rearrange the order.
Edit: fixed.

Yes, that's what he's saying. Unless the echo is IN the IF's {}'s, it will prevent the ELSEIF or ELSE from working. Valid: if (this) { do this } elseif (this) { do that } Invalid: if (this) { do this } echo -a something elseif (this) { do that } Note that anything placed where that echo line is will prevent the ELSEIF from working.

if (% != $null) {
do this
}
else (% == $null) {
do this
} /else doesn't take a condition, so it wouldn't work, would it? Perhaps in future it would be better to post your scripting "bugs" in the Scripts & Popups forum, or spend 30 seconds in a help channel to see if anyone can explain them.

Sorry I meant else { } and elseif( ) { }. It's edited.
I manually typed it... Forgot the if in elseif.
Back to Riamus2.
Wow, weird how the /echo is like a halt or return.
I used the /echo's to debug so I know where the script stops.
That kind of sucks.

Sorry, but I don't get your point. you can debug with echos that easy, and dont have to break the if-then-else structure (?) alias checkvar {
; -stuff-
echo -a START of the if-else statement is reached
if ($eval($+(%,VariableThatDoesNotExist,$me),2) != $null) {
echo -a IF triggers, the var has a value
; -stuff with if-
}
else {
echo -a ELSE triggers, the var has no value
; -stuff with else-
}
echo -a END of the if-else statement is reached (thus no error)
; -stuff that follows, be it if or else above-
}

Wow, weird how the /echo is like a halt or return. No, it doesn't. It does, however, prevent ELSE/ELSEIF from doing anything. Anything else in the script will still happen... just not the ELSE/ELSEIF. If it acted like HALT/RETURN, nothing else would happen in the script. Now, to explain... If ELSE/ELSEIF could have various commands between it and the original IF, then mIRC would have a hard time trying to figure out which IF the ELSE/ELSEIF is supposed to be with. Sure, it could take the first IF preceding it, but that's not a great way to do things. I don't believe any language does it that way. If you break the IF/ELSEIF/ELSE format by inserting commands in the middle, then when mIRC gets to the ELSEIF/ELSE, it will have no idea what you're trying to compare and it will treat it the same as if you never had an IF statement.

Okay that makes sense. I'll have to follow Horstl's way.
Thanks.

Instead of echoing what you want after each /if, you can just have one /echo before the first /if with all information you need, and in this way you'll know which statement have been executed :
echo -a > %a /// %b /// $hget(%a,%b) /// %c
if ($gettok($hget(%a,%b),-3,32)) { }
elseif (%a isin %b) && (%c isnum 8000-9000) { }
elseif ($istok(Ga.is.Ga,$hget(%a,%b),46)) { }
else { }
