How to pass 3 variables from a script into a function and get 1 output?

Hey everyone, I am trying to call a function from a script that basically gives 3 variables and returns 1 result. My function ("GetResult") is already written, it asks which mode (1-6), then goes into an if statement and asks if the user wants a random generated result or a fixed result. if isRand == 1, then random result is generated. if isRand == 2, then they are prompted to enter the Index number, then result is given.

This is all I have so far for an idea on how to call it from another function.

result = GetResult(Mode, isRand, Index);

So my main question is, how can I pull this off? I feel like I need to assign certain numbers to words, Like I can't use 1-6 for Mode, Since this script I am calling it from will be eventually attached to the GUI. I need to say which each mode is. Is this the best way to do this? I was thinking about putting this statment below in my GetResult function. What do you think? Thank you in advance!

if Mode == "AB"
  GetResult(1)
elseif Mode == "CD" || "EF" || "GH"
  GetResult(2)
elseif Mode == "IJ"
  GetResult(3)
elseif Mode == "KL"
  GetResult(4)
end

Where are the letters coming from?

Anyway, if you want to do something like this, you should use strcmp to compare char arrays. A better solution is probably to use switch:

switch Mode
    case "AB"
        Mode=1;
    case {"CD","EF","GH"}
        Mode=2;
    case "IJ"
        Mode=3;
    case "KL"
        Mode=4;
    otherwise
        error('invalid Mode selected')
end
output=GetResult(Mode);

Thank you! This makes sense. When you say:

output=GetResult(Mode);

could I still use:

result = GetResult(Mode, isRand, Index);

and get my single result back?

Absolutely. I would even say that is the preferred way to do it.
