Thanx in advance!

Answer 1

Hi,
The purpose of load of program is to load the program into system memory so that it can be execute the program and also this is the first event in the program. After executing this event only other events is executed. Other events are
Initialization
start-of-selection
get
end-of-selection
etc all other events are triggered.
The purpose of Initialization:
1 . In initialization it is not only the parameters default value
which are required/accessed/controlled
in initialization event.
2. In a program there are so many variables,
the values of these variables
can be set in intiailization event.
3. Such values sometimes cannot be hardcoded.
They may be requried to fetch from database
or do some calculations,
(which is not possible while declaration
data and parameters)
4. Sometimes, some variant can also be imported
for selection screen.
5.This event is invoked directly after LOAD-OF-PROGRAM and before the selection screen processing of any existing standard selection screen.
This gives you the one-time opportunity to initialize the input fields of the selection screen, including those defined in the logical database linked with the program.
When run in background, values initialized in initialization event are considered.
For eg: if you want to initialize like this:
carrid-sign = 'I'.
carrid-option = 'EQ'.
carrid-low = 'AA'.
carrid-high = 'LH'.
APPEND carrid TO carrid.
You cannot achieve this by giving 'default' or 'value' at selection-screen.
Don't forget ot reward if useful.
