Predefined ABAP TYPES

Hi team. I have the following task to complete:

Like in the first exercise of this course, create a new global class that implements interface IF_OO_ADT_CLASSRUN.
Copy the following code snippet to the implementation part of method if_oo_adt_classrun~main( 😞
Code snippet
* Data Objects with Built-in Types ********************************************************************** " comment/uncomment the following declarations and check the output DATA variable TYPE string. * DATA variable TYPE i. * DATA variable TYPE d. * DATA variable TYPE c LENGTH 10. * DATA variable TYPE n LENGTH 10. * DATA variable TYPE p LENGTH 8 DECIMALS 2. * Output ********************************************************************** out->write( 'Result with Initial Value)' ). out->write( variable ). out->write( '---------' ). variable = '19891109'. out->write( 'Result with Value 19891109' ). out->write( variable ). out->write( '---------' ).

I have the following error:
Field "VARIABLE" is unknown.

Please assist. I am a beginner.
Brice.

You have to declare the variable first. I assume the exercise was to figure out which data declaration is the correct one.

Since the variable gets its value later on, variable = '19891109'.

You have to see which one from the following can be

DATA variable TYPE string.

DATA variable TYPE i.

DATA variable TYPE d.

DATA variable TYPE c LENGTH 10.

DATA variable TYPE n LENGTH 10.

DATA variable TYPE p LENGTH 8 DECIMALS 2.

You need only one of the declarations, i wont tell which one. Try it out and see which one works.

Click on the three dots in the editor.

Then click on the </> button.

Then post your code.

* Data Objects with Built-in Types ********************************************************************** " comment/uncomment the following declarations and check the output DATA variable TYPE string. * DATA variable TYPE i. * DATA variable TYPE d. * DATA variable TYPE c LENGTH 10. * DATA variable TYPE n LENGTH 10. * DATA variable TYPE p LENGTH 8 DECIMALS 2. * Output ********************************************************************** out->write( 'Result with Initial Value)' ). out->write( variable ). out->write( '---------' ). variable = '19891109'. out->write( 'Result with Value 19891109' ). out->write( variable ). out->write( '---------' )

so much nicer, don't you think?

In answer to your original question it would really help if you would follow the instructions:

comment/uncomment the following declarations and check the output
