X++ Programming Language Tutorial guide
In this blog we will discuss about some X++ programming syntax. Here we will learn how to write comments in x++, X++ Variable, boolean variable, real variable, date variable, str variable, container variable, if statement, if else statement.
X++ Comments
In this section you will that how to write comments in x++ programming language. There are two types of comments available in x++, single line comments and multiline comments. In the below example you will learn both of them.
Code
<span class="pln"> </span><span class="kwd">static</span><span class="pln"> </span><span class="kwd">void</span><span class="pln"> </span><span class="typ">RummanJob1</span><span class="pun">(</span><span class="typ">Args</span><span class="pln"> _args</span><span class="pun">)</span><span class="pln"> </span><span class="pun">{</span><span class="pln"> </span><span class="com">// This is single line comments</span><span class="pln"> </span><span class="com">/* This is multiline comment */</span><span class="pln"> </span><span class="pun">}</span><span class="pln"> </span>
In this section we will learn about the three types of messages
Code

X++ Variable
In this section you will learn different types of variables in x++ programming language.
