Hi,

In ABAP, every processing block ends with keyword 'END'... For example DO - ENDDO, LOOP- ENDLOOP, FORM - ENDFORM, CASE - ENDCASE.

Do---Enddo

is used in to perform a step in a loop. Normally a conditions is attached with loop sothat looping will continue till condition holds true.

Form ---Endform... is used for defining the subroutines(functions) in the program. The utility of writing codes in FORM - ENDFORM is that the visibility of code block is local to form...

Cheers,

Simha.

Between form-endform we will define the subroutines which is called with perform.

do-enddo is a loop like while etc.

Actually there is no similarity between them to compare fr differences.

do-endo id an endless loop.

the statements in between the do-enddo will be executed until and uless it encounters an exit statement.

form-end-form is the part of code that can be called using a perform statement.

the code insode the form-endf-rm will be executed as many times as the number of times the perform statement is used in the program.

P.S: Please use a meaningful subject in your posts.
