Ki-shell and if

Support
1

Hi,

I trie this script :

var a = 18
var b = 19
var c = if (a>17) b else a
println(c)

and I runned it using kotlinc -script if_test1.kts
result is 19

I tried this and just after typing b (vithout enter) I have got this error :

ki-shell 0.4.5/1.6.10
type :h for help
[0] var a = 18
[1] var b = 19
[2] var c = if (a>17) b
java.lang.NullPointerException
