ABAP Programming Tutorial

When a dictionary object is changed, a program that references the changed object will automatically reference the new version the next time the program runs. Because ABAP is interpreted, it is not necessary to recompile programs that reference changed dictionary objects. This example contains two statements: The program displays a list on the screen.

In this case, the list consists of the single line "Hello World".

Consecutive statements with an identical first leftmost part can be combined into a "chained" statement using the chain operator: The common part of the statements is written to the left of the colon, the differing parts are written to the right of the colon and separated by commas. The colon operator is attached directly to the preceding token, without a space the same applies to the commas in the token list on, as can be seen in the examples below.

In a chain statement, the first part before the colon is not limited to the statement name alone. The entire common part of the consecutive statements can be placed before the colon. ABAP has 2 ways of defining text as a comment:. These statements traditionally used sentence-like structures and avoided symbols, making ABAP programs relatively verbose.

However, in more recent versions of the ABAP language, a terser style is possible. ABAP provides a set of built-in data types. In addition, every structure, table, view or data element defined in the ABAP Dictionary can be used to type a variable. Also, object classes and interfaces can be used as types. Date variables or constants type D contain the number of days since January 1, 1 AD.

Time variables or constants type T contain the number of seconds since midnight.

A special characteristic of both types is that they can be accessed both as integers and as character strings with internal format "YYYYMMDD" for dates and "hhmmss" for times , which can be used for date and time handling.

For example, the code snippet below calculates the last day of the previous month note: All ABAP variables have to be explicitly declared in order to be used. They can be declared either with individual statements and explicit typing or, since ABAP 7. Normally all declarations are placed at the top of the code module program, subroutine, function before the first executable statement; this placement is a convention and not an enforced syntax rule.

The declaration consists of the name, type, length where applicable , additional modifiers e.

In subsequent sections, it goes on to discuss in more detail how these terms are used in ABAP Objects. The end of this section contains a list of further reading, with a selection of titles about object orientation. Internal tables are an important feature of the ABAP language.

The main difference with these languages is that ABAP provides a collection of statements to easily access and manipulate the contents of internal tables. Note that ABAP does not support arrays; the only way to define a multi-element data object is to use an internal table. Internal tables are a way to store variable data sets of a fixed structure in the working memory of ABAP, and provides the functionality of dynamic arrays.

The data is stored on a row-by-row basis, where each row has the same structure. Internal tables are preferably used to store and format the content of database tables from within a program. Furthermore, internal tables in connection with structures are an important means of defining complex data structures in an ABAP program. The following example defines an internal table with two fields with the format of database table VBRK.
