As with all languages, X++ has a specific syntax and semantics that you need to learn to use it. By most standards X++ is an easy language, and if you are a developer this chapter will have you programming in no time. In this section we look at the following: Data types Operators and expressions Methods and variables Classes and objects Language constructs Macros

Data types in Axapta come in three forms: primitive, composite, and extended. Axapta defines the first two and you will recognize them right away, but read their definitions; they are not exactly what you know from other languages. Tables 20-1 and 20-2 list them respectively.

The third type is the kind you can define yourself in the AOT, and is derived from the Extended Data Type class. Because these are not implemented directly in X++, we will look at them only in the section on Axapta classes and objects. Table 20-1. Primitive Data Types

A numerical value without decimals. Defined internally as a long integer. Automatically initialized to 0. A numerical value with decimals. Defined internally as a Binary Coded Decimal. Automatically initialized to 0.0. A representation of day, month, and year. Represented internally as a date. Automatically initialized to null. Math can be performed with integers such as Date = Date + 10, which will increase the data by 10 days. A representation of hours, minutes, and seconds. Represented internally as a short integer. Automatically initialized to 0. A character string that can be of variable or fixed length and left- or right-aligned. Represented internally as string. Automatically initialized to an empty string. 0=false, 1=true; all other values are undefined and you can use the predefined X++ enums false and true Defined internally as a short integer. Automatically initialized to 0 (or false).

Note The documentation from MBS indicates that enums are a primitive data type, but this is not correct;
you can t, for example, declare Enum myEnum.
Table 20-2. Composite Data Types
Data Type
Arrays
Description
A collection of variables of a given data type. Initialized automatically to an empty array. Cannot contain classes or tables. A collection of variables of any data type. Automatically initialized to an empty collection. Cannot contain classes or tables. A definition for an object. Initialized to null. A definition of a record of the table class and equivalent to class variable. All fields are automatically initialized to the default for their respective data types.

Classes Tables
CHAPTER 20 X++
Note MBS documentation does not clearly define composite data types, and can be a little misleading.
The best way to get a grip on how they work and what they are is to write a job that will let you experiment with them.
The basic principles of conversion between data types in Axapta are as follows: Integers are converted to dates in expressions. Primitive data types are implicitly converted upward. Axapta includes built-in conversion functions for explicit conversion between primitive data types. There is no implicit or explicit conversion between composite data types. Classes are implicitly converted to their superclass or explicitly by casting. Tables are automatically converted to a special table class called common.
Operators
X++ supports the operators listed in Table 20-3 in order of precedence, which you will easily recognize. Table 20-3. Operators
Type
Postfix Unary Instantiation Multiplication and division Addition Shift Relational Equality Bitwise Logical Ternary Assignment
Operators
[], (params), expression++, expression-++expression, --expression, +expression, -expression, !, ~ new, (type) expression *, /, %, DIV, MOD *, /, % <<, >> <, >, <=, >= ==, != &, ^, | &&, || , : =, +=, -=
Expressions
Expressions are the building blocks of statements, and they represent a value i.e., their resolution returns a value, and should present no challenge to you if you are a developer. If you really need the details of valid X++ expressions, the MBS documentation includes a complete EBNF (Extended Backus-Naur Form) specification of the X++ grammar.
