From A Beginners Guide to Euphoria:
type fruit(sequence unknown_fruit)
sequence valid_fruit
valid_fruit = {"bananas", "apples", "oranges", "pears"}
return find(unknown_fruit, valid_fruit)
end type
This defines the fruit type so you can use it later

This is wierd to me.
It would make more sense like this:
fruit_check = "pears"
fruit fruit_check
puts(1, "Program Run Completed\n")
or
fruit_check = "pears"
fruit_check = fruit(fruit_check)
puts(1, "Program Run Completed\n")
Please, Why is it structured like this?
Thanks!
using it later
fruit fruit_check --defining a variable of type fruit if fruit("pears") then --test of pears is a fruit puts(1, "Valid fruit!\n") fruit_check ="pears" --fruit check can now be "pears" else puts(1, "Not a valid fruit!\n") fruit_check = "pears" --fruit_check can't be "pears" - will crash the program --add pears to the list of valid fruits end if
