Is there a better way to cross check multiple variables to 1 name, than using an IF statement for each variable to check?

Say I have 30 variables, all with 1 name in each or empty(nothing else). Then I want to see if a captured %1 name matches any of those. Is there a better method to do that, than writing out 30 IF statements? The names for the variables change with any new group.

Say something like this instead

#IF (%1="var1, var2, var3, var4......") {} {}

Instead of 30 IF statements. Then if there is a way, is there a surefire method to determine which variable matches the %1. So I can then use the var instead of %1? For at the end I would need to know which variable matched the %1, to further my script.

Thanks.

I am not sure what you are keeping in those variables, but you should be able to keep them all in a single record variable. See the commands #ADDKEY #DELKEY and the function %db.

Alternately you can keep you current variables and maintain a list of the variables in another variable. See the commands #ADDITEM #DELITEM #FORALL and the functions %ismember %additem %delitem %item
%ismember is likely the closest match to what you asked for with the least additional work.

If this were CMUD I would suggest a #SWITCH.
For zMUD i was thinking along what Vij said.

The simplest way to do what you want, as far as matching goes, is #IF (%ismember(%1,@var1|@var2|@var3|@var4)) {do some nonsense} {do some other nonsense}. I use this to block certain things from going to my chat window so I know it works. The only way to find out what it matched, would be to save your %1 in another variable before the if statement, so it would end up looking more like:
