How do I amend The choose expression

I dont know if there is a way to do this but lets say i have the command

Choose(2,5,7,9) and i want to add 15 on the end

is there a way to amend the choose command and just add the 15 to the end the number 15 could be any anumber depending on what item the number relates

this is why i need to amend and not just change the string thanks for any info i get

i

Not that i know.

But why not use an array?

Choose a random index floor(random(0,array.width))

Have the values on the X-index.

Add values with Array > push

Yes Mate thanks for response , I am Using arrays with push at the moment but amending the choose command would be a whole lot less time consuming for what i am doing. (if theirs an easier quicker way il take it ..)

Choose is limited to a fixed set of numbers. If you need a flexible set, an array is the best choice.
