Macros

Macros 

Macros are constants, or pieces of code, that are being taken care of by the compiler

before the rest of the code to replace the code where the macro is used with the

content of the macro. There are three different types of macros: stand alone macros,

local macros, and macro libraries.

Macros are typically constant values that are only changed by developers. They are

used so that developers don't have to hardcode these kind of values in the X++ code,

but rather refer to the macro.

The macro libraries can be found in the AOT under Macros. Each of them can contain

multiple macros that can be used throughout the rest of AX.

To use the macros from a macro library in AX, simply include them in the scope

that you would like to use them. The next example shows how to use two different

macros from the same macro library in a Job.

First we create a macro library that consists of two macros:

#define.Text('This is a test of macros')

#define.Number(200)

Then we use these macros from within a Job:

static void Datatypes_macro_library(Args _args)

{

// Referencing macro library has to be done in the class declaration

// or in the declaration like in this example

#MacroTest

;

info(strfmt("Text: %1. Number: %2", #Text, #Number));
