Write statement - display on output field

Hi,

I have simply program which calculates sum of two numbers and display results on screen but I would like to display this results in this form:
"Your results is: ____".

Fragments of code:

DATA INPUT1 TYPE i.

DATA INPUT2 TYPE i.

DATA sum TYPE i.

OUTPUT2(1000) TYPE c.

PERFORM function_sum.

FORM function_sum.

  sum = INPUT1 + INPUT2.

  output2 = sum.

ENDFORM.

Example:

input1 = 3

input2 = 4

I wolud like to display "Your results is 7." - but on output field "output2"

Thanks,

Marcin
