Initialization and load of program

Hi ,
Can anybody tell me the difference between initialization and load of program events because both of these events functions in a similar way .
Neetesh

Hi neetesh,
1. In normal programming for se38 reports,
   it does not make any difference between initialization and load-of-program.
2. HOWEVER,
3. Suppose u want to call some FORM in another program
   using PERFORM MYFORM(ZREPORT2)
   and u want to fill some global varaiables of ZREPORT2,
   then WHAT ?
4. In that case,
    when PERFORM is encountered in report1,
    then the ZREPORT2 is LOADED
   and the event LOAD-OF-PROGRAM is fired,
   where we can fill values in global variables.
(in such case, initializatino won't be fired)
regards,
amit m.

Difference between Initialization and Load-of-Program

Hi All!
Could anybody tell me what exactly is the difference between Load-of-program and initialization using a sample program?
Thanks in advance...
Jag.

Hi Jag
It seems not so much difference. But INITIALIZATION block is peculiar to executables.
<b>INITIALIZATION</b>: Only occurs in executable programs. The ABAP runtime environment triggers the INITIALIZATION event before the selection screen is processed, at which point the corresponding event block is processed.
<b>LOAD-OF-PROGRAM</b>: When an ABAP program is loaded in an internal session, the runtime environment triggers the LOAD-OF-PROGRAM event, and the corresponding event block is executed.

1) WHAT if I juse JUST ONE Adobe program pretty often?
They have a single use subscription for $20/mo. Similar to upgrading extended version every 1.5 years.
2) WHAT if I created projects like 2 months ago and I didn't use Photoshop for a full month. Who assures us that with the CC series the projects are opened with the old CS ones?Or don't use it every day?
Same problem if you own it. If upgrade price is $400 every 1.5 year that is same as $16/month. You can choose not to update and version will be same as when you last used it.
3) WHAT if I don't use Adobe 24/7? and 5) Making an day-based subscription?? Same problem if you own it. If upgrade price is $400 every 1.5 year that is same as $16/month.
4) Adobe, do you think to be the only one making these softwares?
Competition is always a factor in market.
6) After all this mess, you discriminate Europeans, too?
Taxes charged by Governments and municipalities are not controlled by Adobe.

Illegal scam has informed me Firefox out of date (it isn't) and loaded a program for me to run. BEWARE 31-01-2012 16.45 UK

Don't know how to contact Firefox so using this method.
Please pass on warning of scam

Page appeared on the first click on a very reputable site (deliaonline.com/recipes/) that I use often.
As happens with these scams it wasn't there on reload. Scam page was similar to a Firefox info page in style, but not as well designed. Could easily fool those unaware.
'Run' window appeared and self loaded an .exe program then prompted me to install.

Diff betw Load-of-program and Initialisation

Hi,
can anyone give me in points the Diff betw Load-of-program and Initialisation events?
Useful answers wil b rewarded.
Thanx in advance!

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.

Varun.

Difference between Load - of - program & Initialization ?

Hi Friends,
What is the "Difference between Load - of - program & Initialization "
Cheers
R.Kripa.

The corresponding event is triggered in an internal session immediately after a program with type 1, M, F, or S is loaded. The corresponding processing block is processed once per program and internal session.
The processing block LOAD-OF-PROGRAM has approximately the same function in an ABAP program with type 1, M, F, or S as the constructor method of a class in ABAP Objects.
Programs wiht type 1, M, F, or S can be loaded into an internal session in two ways:
Program calls
Whenever you call a program using SUBMIT or a transaction code, a new internal session is opened. The LOAD-OF-PROGRAM event is therefore called in each program call.
External procedure calls
The first time you call an external procedure (subroutine or function module), the main program of the procedure that you called is loaded into the internal session of the calling program. The eventLOAD-OF-PROGRAM is triggered and the corresponding processing block is executed before the procedure that you called. However, subsequent calls from the same calling program to a procedure in the same subroutine pool or function group do not trigger the LOAD-OF-PROGRAM event.
so it's before the program is loaded in the memory for execution.
Initialization:
(For executable programs of type 1), the associated event is executed before the selection screen is displayed.
The parameters (PARAMETERS) and selection criteria (SELECT-OPTIONS) defined in the program already contain default values (if specified). You can assign different values here and also change the database-specific selections.
Example
Define the last day of the previous month as the key date:
PARAMETERS QUAL_DAY TYPE D DEFAULT SY-DATUM.
INITIALIZATION.
QUAL_DAY+6(2) = '01'.
QUAL_DAY = QUAL_DAY - 1.
Here, the default value of QUAL_DAY is the current date, e.g. 05.04.88 (QUAL_DAY = '19880405'). Two subseqent statements set the date first to the beginning of the month, e.g. 01.04.88 (QUAL_DAY = '19880401') and then, by subtracting one day, to the last day of the previous month, e.g. 31.03.88 (QUAL_DAY = '19880331').
so load-of-program before program is loaded in the main memory is excuted and initialization is done before selection screen of the program is displayed..
reward points if it helps

My macbook is loaded with microsoft work and every time I try and open the program I get an error reading and it will not open. Powerpoint and the other applications still respond!

my macbook is loaded with microsoft word for macs and every time I try and open the program I get an error reading and it will not open. This is what it says:
The application Microsof Word quit eunexpectedly. Powerpoint and the other applications still respond!

The joys of Microsoft!
Maybe the preferences file is corrupted. You should be able to find the Word preferences file in the folder:
your user name/Library/Preferences
Its name is com.microsoft.Word.plist
I suggest you drag this another folder and try Word again.
If that doesn't work then you might find clearing the cache files will fix the problem. You can do this manually but I never bother. Instead I use a program like Snow Leopard Cache Cleaner (shareware) or Onyx (free). These programs do lots of other maintenance jobs so it's worth having at least one of them.

Sounds like you downloaded the OS X Mavericks 10.9.5 Update or Combo Update. Neither will work on a version of OS X prior to OS X Mavericks. Those are only used to update an existing install of OS X Mavericks. The Combo will update any version from 10.9.0 thru 10.9.4. The Update will only update version 10.9.4.
You need the full installer of OS X Mavericks from the App Store. However, the App Store no longer offers OS X Mavericks. Yosemite is the new FREE OS X.

I upgraded to Mavericks and now I get a LOT of the spinning colored disk when loading a program or almost anything.

I have accidentally deleted off my Mac a preferences file for Adobe photoshop and now the program cannot initialize. I have talked to Apple and then say that if Adobe can isolate the file they can help me restore it from my time machine. How do I isolate the file ?

Do you have the path to this file and name of this file?

I just downloaded the Java software update and now certain programs aren't loading that use Java?

So I downloaded the new softeware update and now my programs that use Java won't load. Does anyone know what I can do.

Due to the extreme unpredictability of the Flashback Trojan, that was constantly changing (and a new variant that's been detected and seems to be worse), Apple decided to play it safe just in case the revised Java code was still vulnerable. So, Java is disabled by default for applets and must be manually enabled as needed (with the warning about possible vulnerability).
So, head on over to Java Preferences, in Utilities, and enable the thing as needed. Disable when no longer in use for security's sake. BTW, if you enable but don't use Java in awhile, it is configured to self-disable for the same reason.

Moving Programs with a full erase and load of Tiger

I have a G4 iBook with Panther, I bought Tiger and want to do a full erase and load Tiger fresh. The problem is I have lost my Office 2004 Mac CD and I dont want to loose these programs. Being a fairly new Mac user, is there a simple way to "Back Up" my programs and reload them on Tiger when I do a full erase and load?
Thanks in advance.

Hello Will,
Do you have access to an external drive? A firewire one? If so you can use something like..
Carbon Copy Cloner
or
Super Duper
Both are easy to use and will do that which you seek to accomplish.

Ian
