Looping integer

In vb.net there is this codes or something like this which I forgotten already:
Dim a as integer
a = 0
loop
a+1
end loop
clear a
Is it possible to do like this code in ABAP way? If there is, please show me the codes.

Hi JuzMe
The same code is not worked in ABAP.
There is another way by using
do.... endo, loop at ITAB.....endloop.
data: count type i.
count = 20.
do
count = count + 1.
if <condition>
exit.
endif.
enddo.
In your requirement it goes infinite loop.
We have to incorporate condition within the loop to prevent infinite looping by using EXIT statement.
Reward me if useful.

How to correctly specify the integer values in the following Loop command?:LOOP (integer, [break])COMMANDS ;ENDLOOP For I don't know why they use "30" in LOOP(30)."FIX("New York",Camera,Actual,Mar) LOOP(30) Commission = Profit * .15; Profit = Margin - "Total Expenses" - Commission; ENDLOOP;ENDFIX"

Loop and endloop in smartform - if you want to print multiple data for each header ,then we need to use..
one example : i have sales order - order may contains more than one item..if you want to print multiple items then we need to go for loop endloop.
Program lines - without effecting program - we can change the code within smartform( I mean we can pass the values and get the values based on condition )
i am getting material number from program and i am printing here,later on customer is looking for material description,then you can write simple code within samrtform by using program lines.

Numeric or value error Line 410??? appending to lob

line 410 is marked with line of '%%%%%%%%%%%%%%%%%%%%%'
This script is designed to profile data in a set of table by generating sql and running it with an execute immediate. It works by generating a set of code for each datatype and then executing the code twice for each table. Once for the summary profile and once for the detail profile. I've been starting at it awhile and can't figure out what the error means??? Thanks in advance!

dbms_lob.writeappend(c, length(e),e);
execute immediate to_char(c);
end loop;
end;

Most likely issue is:
execute immediate to_char(c); TO_CHAR will raise numeric or value error if c exeeds 4000 bytes. What Oracle version you are on? In newer versions execute immediate supports CLOB, so you can chnege the above to:
execute immediate c;Keep in mind, execute immediate has 32K limit on SQL string.

Hello,
I am a novice programmer and my program does not check for strings and numeric characters. Below is my program, please give me some feedback, as soon as possible. Thanks a lot

You didn't indent your code, so that makes it hard to read, and there's a lot of it that has nothing to do with what your question might be. But you want feedback? Well you are "validating" the student's first name in a strange way. A letter followed by any characters that aren't digits -- for example, "a++?" would pass. And that validation will fail if an empty string is provided, because "charAt(0)" assumes there is at least one character. I would just check it isn't blank. And I would provide a meaningful error message. "Invalid Entry" is unhelpful as it doesn't tell the user what is wrong with the input.

using arrays is pretty simple. You may want to clean up your code a bit, and place declerations outside of the main method, and create some smaller methods that dow rok, rather then having main carry the whole load. try something like this:
public class GradeWatch9
Student [] studentFile=new Student[50]; /*makes an array with 50 cells
*here I used another class, Student, which you will have to write. the Student class could be as small as two data fields, String name and int grade.
public static void main ( String args[] )
     for(int i=0;i<studentFile.length;i++)
         String name=getNextName(); //method you write to get the name
         studentFile=new Student(name);
int grade=getGrade(); /*method to get and calculate grades*/
studentFile[i].setGrade(grade);
getNextName()
//gets the students name
getGrade()
//gets and calculates grade
public class Student
int grade
String name
Student(String n)
name=n;
public void setGrade(int g)
grade=g;
see if that helps a bit :)

You should use a List instead, it will be more maintainable if you want this program to work for more students, without having to edit the souce:
List students = new ArrayList(); // Create a List
// To add students
students.add(student);
// To iterate through them
Iterator it = students.iterator();
while(it.hasNext)
Student s = (Student)it.next();
// For direct access
Student s = (Student)students.get(index);
class Student extends Object
private String firstName;
private String secondName;
private String id;
private String midtermGrade;
private String finalGrade;
public Student()
// Add a setter/getter for each variable
also override toString()
now with this bean, you could open an option pane passing a JList that was create with the passed in List

Output integer loop

I'd like to create a sub VI that uses a for loop to spit out an integer. I want to set up a handful of boolean controls, each corresponding to an integer (say 1, 2, 3). When none are true, the output of the sub VI is 0, and when one of the controls is switched to true, the output will be 1, 2, or 3. Any suggestions?

One possibility is to use radio buttons.

Suggestion: Macros or a way to unroll loops? Integer array input? Shader Model 3 and 4?

I think it would be nice if pixel bender supported a way to unroll loops. In it's current state certain shaders are really awkward to write or just get ugly when they're converted for flash player. I know it wouldn't be that hard for the developers to just unroll constant sized loops. Things such as:
for (int i = 0; i < 10; ++i)
if (foo) { ... }
can be unrolled easily. Either that or add in some code generation feature that allows this with a preprocessor system. Or better yet add in support for loops since it only requires shader model 3 or equivelant from GLSL.
This brings me onto another point. Is there going to be support for Shader Model 4? I'm talking about bitwise operations and integer types. Even if you don't allow native support for byte array adding texture sampling for bytes, shorts, and integers would be nice. Also allowing this to work in flash would be nice with the ability to tell the user they don't have shader model 4 or be able to detect compatability and use a different shader.
Integer arrays would be nice to allow to as input then to the shader. I noticed the reference manual already mentioned:
"NOTE: Pixel Bender 1.0 supports only arrays of floats, and the array size is a compile-time constant. Future versions of Pixel Bender will allow arrays to be declared with a size based on kernel parameters, which will enable parameter-dependent look-up table sizes."
Again support for these features in flash player would be really nice.
Targetting the lowest GPUs is really limiting the true power of pixel bender. I wrote this for fun: http://assaultwars.com/pictures/raycasting6.png which is just a simple real-time voxel raycaster. However, it could be so much more powerful if pixel bender supported more of the GPUs features. Even simple things like custom functions would be really handy in flash player. I'm thinking of this more oriented toward flash games too where more powerful features are unlocked based on the user's GPU.
If this is already planned for a future pixel bender release then nevermind. I didn't see a developers blog or any news about future versions.
Interesting:
http://forums.adobe.com/thread/36659?tstart=60
Apparently Kevin said "Look for them in a future version of the language as cards that support these features become common." in regards to bitwise operators aka Shader Model 4.

Here's an example, not using NetBeans:
import javax.swing.*;
public class TextDemo extends JPanel
    public TextDemo()
        int[] newbinarray = {0, 1, 1};
        StringBuffer sb = new StringBuffer();
        for (int value : newbinarray)
            sb.append(value);
        String st = new String(sb);
        this.add(new JTextField(st));
    private static void createAndShowGUI()
        JFrame frame = new JFrame("TextDemo");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.add(new TextDemo());
        frame.pack();
        frame.setVisible(true);
    public static void main(String[] args)
        javax.swing.SwingUtilities.invokeLater(new Runnable()
            public void run()
                createAndShowGUI();

ORA-01403: Not found any data
ORA-06512: line 11But I Know why is it, the department_id numbers are (100,110,120,130,140,150,160) and the first loop it's ok but
in the second loop the 101 department_id doesn't exist an then it fails.
what can I do to resolve this error?
thanks in advance!!

Incrementing Ascii and integer loop

Hi there,
Just wondering if anybody can help me with this little problem that I have... I'm trying to write a loop that increments ascii and integers. It should look something like this:
0 1 2 3 4 5 6 7 8 9 A B C D ..... X Y Z 00 01 02..... 0A 0B 0C .... 0Z 10 11 .... ABCD1 and so on...
I got the loop bits but I don't know what I can do to combine the 2...
         for (char x= 'A'; x <= 'Z'; x++)
               System.out.println("Count is:" + x);
         for(int i=1; i<11; i++){
               System.out.println("Count is: " + i);Can anybody give me some tips please? Thanks in advance!

you can do this you know
for(int i=0,char a='a';i<11,a<='z';i++,z++)and then print whatever you want to

Display contents of a loop with time gaps in between

Hi,
I have a peculiar problem.
Consider a "for" loop
for ( i in 1..10)
In the above loop i want to display each value of "i" after a certain time span ( say, 1 sec).
In java, i could have used a "delay" function,but i do not know as how to achieve the same in javafx.
Please help me.
Thanks in advance.

Something like that probably:
def seq:Integer[] = [1..10];
var bound:Integer = 0;
def anim:PauseTransition = PauseTransition {
duration: 1s
repeatCount: sizeof seq
action: function():Void {
    var m:String = "";
    for (i in [0..bound]) {
      m = "{m} {seq}";
msg = m.trim();
bound++;
anim.play();

Display contents of a loop in SCENE

Hi all,
Can i display the contents of a for loop one after another in a "Scene".
The code below displays the contents of "for" loop in OUTPUT window as well as in the "SCENE". But the problem is that the contents of "for" loop are displayed in the scene graph only after the for loop exits.
how can i rectify this code to generate the output similar to the OUTPUT window in SCENE graph.?
import javafx.scene.Scene;
import javafx.stage.Stage;
import javafx.scene.text.Text;
import ranno.*;
import javafx.scene.control.Button;
import javafx.scene.Group;
import generateResult.*;
var number: Integer[];
var msg : String ;
var a : String[];
var locX: Integer;
var locY: Integer;
def canvas = Group { };
var display : Button =Button {
translateX: 100
translateY: 100
width : 100
height : 30
text : "Click"
var text : Text
action:function(){
delete canvas.content;
for(i in [0..1])
java.lang.Thread.sleep(1000);
number=i;
println(number[i]);
a=Integer.toString(number[i]);
locX=20;
locY=20;
msg = "{a}";
text = Text{
x: locX
y: locY+20*i
content : msg
insert text into canvas.content;
Stage
title: "Numbers"
var array : String[];
var i : Integer;
scene : Scene
width: 400
height: 200
content :
[display,canvas]
If you haven't understood my question,please execute this code and compare the output in the OUTPUT window with the SCENE output.
I want the output in SCENE to be similar to the output in OUTPUT window.
Please help me in modifying my code .

Since you haven't used the CODE button, the source code is messed up (star means bold here).
But the short answer is: don't use a loop with sleep()!
JavaFX provides Timelines and Transitions to animate things and add stuff progressively to the scenegraph.

Need help with retrieving data in vector using for-loop

ok for my code, i type in String name, password, phone number and int currentsalary and desiredsalary into the textfields and click Add, and it goes into the vector and name appears on the JList ApplicantList.
what do i add to my listselectionlistener so that by clicking on the name, i can display the details of the person whose name is in the list, back on the texfields?

ok i added that part inside my listselectionlistener
it says incompatible types in line 421.
and where do i insert :
StoringData selectedPerson = detailMap.get(selectedName)
and/or
StoringData selectedPerson = ApplicantList.getSelectedValue()
this is what the code looks like after i added the loop u gave me
