ABAP Words, Overview
ABAP words are the vocabulary of the ABAP language. ABAP statements are composed of ABAP words, operands, and operators according to defined syntax rules. ABAP words are taken from the English language and are grouped into ABAP language elements and into ABAP language element additions that express the semantics of a statement. In addition to letters, ABAP words can also contain hyphens ( -) to form multiword expressions. In addition to the ABAP words, some operators are also made up of letters.
The first ABAP word of a statement is the ABAP keyword. The remaining ABAP words are then additions to a keyword. A single ABAP word can be used both as a keyword and as a non-keyword. For example, DATA is used as a keyword as well as an addition to other keywords. Not all statements are introduced using a keyword or contain ABAP words. For example, assignments with the assignment operator = or method calls do not contain a keyword and do not necessarily contain another ABAP word.
ABAP words are not reserved names as they are known in other programming languages. Although the use of an ABAP word for user-defined identifiers is not forbidden, it should be avoided if possible. Even if this rule is followed, such a situation can occur if new language elements are introduced. Therefore, suitable naming conventions should be observed for user-defined identifiers to avoid conflicts with language elements.
The following table contains all ABAP words of the current ABAP language version, the names of built-in data types, and the names of operators that consist of letters. Names in ABAP programs are not case-sensitive. dummy
