===Passing Arrays By Reference===

By default arrays passed by value. Here in make() we read reference in a variable A, which interpreter put then pointer to array, so it is a kind of reference (like in C). Using & we have normal reference. A ++ operator in a pointer of array add one to each element.

<lang M2000 Interpreter>

Dim a(10)=1

Print a() ' 1 1 1 1 1 1 1 1 1 1

make(a())

Print a() ' 2 2 2 2 2 2 2 2 2 2

make2(&a())

Print a() ' 3 3 3 3 3 3 3 3 3 3

Sub make(A)

A++

End Sub

Sub make2(&a())

A=A()

A++

End Sub
