Hello,

I am trying to figure out how I can use a random generated number to link to a string. For instance if I have 3 cities and a quest is for someone to begin randomly from A, B or C to arrive in A, B or C, I cannot figure out a way to print "Go from city " (A, B, C,) "And arrive at City "(A, B, C).

Is the secret in arrays or something? My effort used strings, such to say
City1$ = A

etc.

Therefore
I need convert (RND) 1, 2 ,3 to city names within a sentence. "Go from " "to " etc.

I can't find the technique in the tutorials. Any help is appreciated.

Thanks

Sardine,

Let's use a single string array, named cityname$(2), which as you can see has 3 slots(0 is also a slot).



Now, fill the array with the names of the cities, each into a single slot.



The RND function will return a number between 0 and the number you supply it. Therefore, rnd(2) will return a number between 0 and 2, making a match to either slot of our array.

Below is the end of the code. Concatenate the chosen array slot string into the middle of your constant strings.

Thank you NanoBrain

Just what I was looking for. Much simpler than what I had in mind.
