Simply create an inline array, iterate through and assign values.

listOf(a, b, c, d).forEach { it = "Text" }

Not possible in Kotlin (unless you are ready to resort to some contrived constructs with repetition as described in other answers and comments). You cannot even write

    a = b = "Text"

because weirdly enough, assignments are not expressions in Kotlin (as opposed to almost everything else like if, return, throw, swicth, etc., which are expressions in Kotlin, but not in Java, for example).

So, if you want to assign exactly the same value without repetition (of the assigned value), you'll have to write

    a = "Text"
    b = a

Note, that there is also an also function (pun intended), so technically you can write the following if you really want to stay on one line

    a = "Text".also { b = it }

but I doubt it is really worth it.

var a: String? = null; var b: String? = null

or

var (a: String?, b: String?) = null to null

But please don't ever do so
