DEFINE
Basic form
DEFINE macro.Effect
Defines a program component (macro) under the name macro . It must consist only of ABAP/4 statements and is expanded at compilation time.A macro should always be concluded with the END-OF-DEFINITION statement.
In the definition, you can use &n to reference positional parameters (n = 0 .. 9). When the macro is called, &n is replaced by the n-th actual parameter.
Example
Define a macro called "++" for use in the program.- DEFINE ++. ADD 1 TO &1. END-OF-DEFINITION. DATA: NUMBER TYPE I VALUE 1. ... ++ NUMBER.
Notes
- In general, it is better to use subroutines (FORM , FUNCTION ) rather than macros because subroutines - unlike macros - are supported by all the ABAP/4 Development Workbench tools (including debugging, runtime analysis, runtime error handling, ...).
- You cannot nest macro definitions.
