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);

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