I was trying to make an alias that when I type glist pop would populate a list of all the roomids from every zone in my map. When I didn't type glist it would echo the populated list to the screen.

Every thing was going fine and dandy tell I tried to make the if statement check to see if pop is in the first parameter.

alias
name: glist
commands:
#if ("%1"=pop) {#echo hi}

Now this works.
could some one explain to me why that works and nothing else I tried seemed to work at all?
#var dummy ""
#var gotolist ""
#gauge pop "Populating List" {@dummy} {%numrooms} {0} {} {hi,red} {} {}
#loop %numrooms {
#add dummy 1
#if (%null( %roomid( %i))=0) {
#additem gotolist %roomid( %i)
#echo ~>~> added room %i as %roomid( %i)
}
}
#unbutton pop
}
Is there an easier way to do this?
Also is there any difference between %numroom and %numrooms?

How can we explain without knowing what else you tried? Presumably, everything else you tried didn't work because you had errors of one kind or another.

Yes, there's a difference between %numroom and %numrooms. %numrooms is a defined function when used with parentheses and might be recognized as a system variable without them. %numroom isn't defined or recognized either way.

You could eliminate the second #IF and just remove any blank item when you finish the loop. There won't be more than one, since #ADDITEM doesn't add duplicates.

#AL glist {
#IF ("%1" = pop) {#ECHO hi}
#VAR dummy 0
#VAR gotolist ""
#GAUGE pop "Populating List" {@dummy} {%numrooms()} {0} {} {hi,red} {} {}
#LOOP %numrooms() {
#ADD dummy 1
#ADDI gotolist {%roomid( %i)}
#ECHO ~>~> added room %i as %roomid( %i)
}
#UNB pop
#DELI gotolist {}
}

Don't know if there's an easier way or not.

I had also tried
#if (%1="pop") {#echo hi}
#if ("%1"="pop") {#echo hi}
#if (%1=pop) {#echo hi}

Thanks for the help on the other stuff tho lightbulb, it helped alot.

Why don't you start by replacing the #if line with simply "#ECHO %1" or "#ECHO %param(1)" and see what it actually contains. If screen space is at a premium or a trigger might be affected use #INPUT instead of #ECHO.

If your inputing from the command I don't see how any of the 4 would have any problems. While quotes on both would generally be reccommended you have a lot of control over the contents of %1 and can get away with no quotes at all. So I have to assume that the alias is actually being called from another script or may have some simple issue like the case, meaning you did "glist POP" or "glist Pop" at the command line.
