How to use if.. else.. statement in Call Function

Hi All,

May i know how to use if else statement in Call Function? I need to create another language for textline1 = 'PLEASE SELECT REASON FOR CHANGE'(006) in Norwegian.

How to create a new variable that would hold the different texts for different language?

IF NOT i_spopli[] IS INITIAL.

DO.

CALL FUNCTION 'POPUP_TO_DECIDE_LIST'

EXPORTING

mark_flag = ' '

mark_max = 1

start_col = 80

start_row = 5

textline1 = 'PLEASE SELECT REASON FOR CHANGE'(006)

titel = 'REASON FOR CHANGE'(002)

IMPORTING

answer = l_ans

TABLES

t_spopli = i_spopli

EXCEPTIONS

not_enough_answers = 1

too_much_answers = 2

too_much_marks = 3

OTHERS = 4.

CLEAR i_spopli.

LOOP AT i_spopli WHERE selflag EQ 'X'.

ENDLOOP.

Thanks.
