Add 2 strings together

Hello,
i have a really weird error message here:
say I define 2 dta type c objects:
data: tot_str(50) type c,
      sub_str(20) type c.
then I do
    tot_str = 'ABCDEF' & substr
assuming both tot_str and sub_str are already initialized.
However, the error message I got is:
Incorrect arithmetic or bit expression: Instead of "&", an operator (+,     -, *, /, ... or BIT-AND, BIT-XOR, BIT-OR) was expected.)
Why is it so? I thought & is the standard concatenation character for ABAP. And BTW, when I changed to +, it will give me a run-time error saying that the 2 strings can not be added....
Thanks a lot!
Regards,
Anyi

Hi Anyi,
yes you are right. I found it in SAP help hidden somewhere in the data objects section:
"If you want to enter a character literal in the ABAP Editor that is longer than a single editor line, ABAP syntax allows you to enter several character literals and link them using the & character. "
So this was just a crutch to bypass the (meanwhile obsolete) editor line length limit.
I the section "Processing Character Strings", chapter "Concatenating Character Strings", they say:
"The CONCATENATE statement combines two or more separate strings into one.
CONCATENATE <c1> ... <cn> INTO <c> [SEPARATED BY <s>].
This statement concatenates the character fields <c1> to <cn> and assigns the result to <c>. The system ignores spaces at the end of the individual source strings.
The addition SEPARATED BY <s> allows you to specify a character field <s> which is placed in its defined length between the individual fields."
That means that all leading and trailing spaces will disappear except the ones in the separator string <sep>.
So it depends on the result you want as how to do the concatenation. if you want a fixed position regardless of blanks, then you must work with offset and length addition.
Kind regards,
Clemens

How do I add strings together with JSTL?

How do I add strings together with JSTL?
Thanks,
JN

Just include them together in an expression string.
For printing
<c:out value="${user.lastName}, ${user.firstName}"/>
or with a set statement
<c:set var="fullName" value="${user.lastName}, ${user.firstName}"/>

Putting 2 strings together

Dear Colleagues
I have a short piece of coding I would hope for some advice on.
public class ReadTest {
public static String readString() throws java.io.IOException {
java.io.BufferedReader in =
new java.io.BufferedReader(new java.io.InputStreamReader(System.in));
return in.readLine();
public static void main(String args[]) {
try {
System.out.println("Enter a string: ");
String inputValue = ReadTest.readString();
System.out.println("You entered: " + inputValue);
} catch (java.io.IOException e) {
System.out.println("An error occurred!");
I have compiled this and was invited on the DOS screen to:"Enter a string". But where do I enter the string?
Then I need to modify the program a little to read two strings and to ensure that the first string ends with the second string. Do I then take it that once I have grasped the fundamentals of joing 2 strings together, that that is the normal rule?
Hopefully, I will begin to understand the code with some help here.
Best wishes

Add String to JNDI Tree

I'm coming from a Glassfish/Tomcat environment where we can add Strings directly to the JNDI tree. What we would like to do is add "config/env/dev" to the JNDI tree so that we can use Spring to determine which environment we are in based on this setting in each node in the cluster environment. From there, we use CommonsConfiguration to manage our environment specific settings in our applications.
Can someone tell me how I can add a string variable as such to the JNDI tree in WebLogic 10.3?
Thanks,
Lou

Generate n sine waves and add them together

Hi
I'm new to Labview and I want to generate n number of sine waves and add them together to form one signal that can be out put through a DAQ card. Each successive wave frequency will be the multiple of a base wave all will be the same amplitude.
This to me suggested a For loop with a sig generator and a passback in it but when I tried this it threw an error because the dt were different.
Any help will be appreciated.
Thanks

Add String to array

I have an array:
private static Person[] names;
names= new array[10];
How do I write a method to add Strings to the array

Hi
Well you could have a variable inside the class which tells you how many slots are filled up.
Then in your addString method you would just use this variable as the index, and then increment the index.
Its best that you use an array if the number of elements are known, on one hand you will get the benefit of strong typing (Vector will take an object and you will have to typecast the object back before using it), and on the second hand it will be much faster

How to make it?
My text-file is big - nearly 65MB..
I'll be happy, if you can give example..

This file allows you to add to already available file, but if not available, it will be created.

Add numbers together from a file

I need to be able to determine the difference of each number from the average and square each difference and sum all the differences.
I found out that the average of the numbers from the file (7 4 5 9 10) is 7. i just need to minus each number from the average then add those numbers together.

            System.out.println(line);
            Placeholder = Placeholder + 1;
            Totalnumber= Totalnumber + line;
            for (count=0; count < Placeholder; count += 1){
                Difference =Difference + Math.pow((line-(Totalnumber / Placeholder)),2);
            System.out.printf("There are "+Placeholder);
            System.out.printf(" numbers");
            System.out.println("");
            System.out.println("");
            double Average = Totalnumber / Placeholder;
            System.out.printf("The total value= "+Totalnumber);
            System.out.println("");
            System.out.println("");

}so far it displays the average correctly. i just need to find out how to loop the equation for finding the distance.
To me my loop looks like it would work. where should i go from here?

while (in.hasNextInt()){
line = in.nextInt();
System.out.println(line);
Placeholder = Placeholder + 1;
Totalnumber= Totalnumber + line;
for (count=0; count < Placeholder; count += 1){
Difference =Difference + Math.pow((line-(Totalnumber / Placeholder)),2);
}so far it displays the average correctly. i just need to find out how to loop the equation for finding the distance.
To me my loop looks like it would work. where should i go from here?You have a for-loop inside your while-loop. The first item through the while-loop your for-loop iterates 1 time; the second time through your while-loop your for-loop iterates 2 times; the third time through your while-loop your for-loop iterates 3 times; ...
I do not think this is what you want. I'm not sure you need the for-loop at all.

How do I add variables to different checkboxes without using the 'Export Value' and then add them together (if checked)?

Hello,
I am very new to JavaScript. I would like to create a checkbox with a numerical value variable activated if the box is checked. Unfortunately, I cannot use the 'Export Value' because I already need to use it for something else.
Any help is really appreciated.
Thanks,
Robyn

Brace yourself, here's your solution.
First of all, the export value of you checkboxes should definitly be the number of hours for the class since you will just add them up further.
Second, we will use the userName property for our second export value (its the field right under Name and its labeled "tooltip"). You will name the class there.
Finally, you need to name each checkbox with a number at the end starting with 1 all the way to 190. This will be used in loops. ("whatever.1", "whatever.2,....."whatever.190")
In the calculate event of "total hours":
var sum = 0; //declaring a variable that will be used in the loop
for (var i = 1; i <= 190; i++){    //this loop will scan through all your checkboxes
     if (this.getField("whatever."+i).isBoxChecked(0) == true){ //if box is checked....
          sum += Number(this.getField("whatever."+i).value);   //.....add its value to the sum
event.value = sum; //display the total
Now for the course name field, we will use the same pattern in the calculate event
var courseList = new Array(); //declaring an empty array that will contain the courses
for (var i = 1; i <= 190; i++){    //this loop will scan through all your checkboxes
     if (this.getField("whatever."+i).isBoxChecked(0) == true){ //if box is checked....
          courseList.push(this.getField("whatever."+i).userName);   //.....add its userName (tooltip) to the array
event.value = "You are attending these courses: "+courseList.join(", ")+"."; //display the array by turning it into a string and joining its items with ", "
You can try it out with just a few checkboxes at first. Don't forget that the loop mustn't go further than the existing field or you will get an error and the script will stop. Make sure no error show in the console (ctrl+J).

Unless the result of your XMLELEMENT query is valid XML adding that string won't accomplish anything. The result will NOT be valid XML.
See my replies in this thread
Re: expression must have same datatype
If your query result is a string then you use || to concatenate strings so just do that in your query.
SELECT 'abc' || 'def' FROM DUAL;
select '<?xml version="1.0" encoding="UTF-8"?>' || XMLELEMENT . . .

Masterdata upload - Add string after conversion

Hi experts,
I upload masterdata from BW using transformationfile and conversionfile. To create a BPC specific ID I need to remove the leading zeros first (using js:parseInt in conversion) and afterwards I need to add a string (VK) at the end of the ID. How can I do that. Using *Str(VK) in transformation will lead to an error as the js:parseInt statement in the conversion file will no longer work.
Any help appreciated.
Thanks in advance
Felix

Hi Flex,
You can achive this by using end routine badi.
LOOP AT <lt_data_im> ASSIGNING <ls_data>.
Get ID value
ASSIGN COMPONENT `ID` OF STRUCTURE <ls_data> TO <lv_id>.
IF sy-subrc <> 0 OR <lv_id> IS INITIAL.
CONTINUE.
ENDIF.
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT'
    EXPORTING
      INPUT = <lv_id>
    IMPORTING
      OUTPUT = <lv_id>.
Concatenate your string to <lv_id>
ENDLOOP.
Thanks & Regards,
