Regarding INitailization event.

Question

Hi All,
Using INITIALIZATION event we can give default input value to selection screen in range.
but we can give like this also(parameters: file like table-field default 1000 and for select-option also ) then what is the use of initialization event .
and
by using parameters we can give a value for single field,
select-options :we can give in put value in range but we can display the single field in select-options using no interval .
so insted of using parameters we can use select-options for single vale and for multiple value then what is the use of parameters.
Thanks,
sheik.

Answer 1

Hi Sheik,
Agree with previous posting that in INITIALIZATION, we can INITIALIZE all the variables we have, for example internal tables,
working areas, counter, flags (boolean), etc. So it's not just to give the selection screen parameter or select options, but all the variables which are not shown on the screen.
And for select options, it is true that we can restrict it to single value with NO-EXTENSION and NO INTERVALS.
But when the design of the program expects only single value to be inputted, why would we bother to process the range/internal table in the select options? And also, select option needs extra memory to allocate instead single parameter entry.
Just my 2 cents
