X++ runtime function resources
This article describes the X++ run-time functions.
The X++ language provides nearly 200 system functions that aren't part of any class and are executed at run time. Run-time functions are used for data type conversions, mathematical operations, and so on. Here are some common run-time functions:
- str2Int – Creates an int value from a str value.
- abs – Creates a positive real value from a real value that is either positive or negative.
- conFind – Retrieves the location of an element in a container.
The logic of the X++ run-time functions is also implemented in the following .NET assembly.
Microsoft.Dynamics.AX.Xpp.Support.DLL
Inside this assembly, the X++ run-time functions are implemented as static methods of the following class.
Microsoft.Dynamics.AX.Xpp.PredefinedFunctions
The following table lists and describes only the categories of X++ functions. These categories are intended to help you understand the many functions. However, the categories don't represent any formal construct.
Category | Description |
---|---|
Business | Functions that enter financial data and calculate formulas. For more information, see X++ Business Run-Time Functions. |
Container | Functions that operate on the container data type of X++. For more information, see X++ Container Run-Time Functions. |
Conversion | Functions that translate data of one type into data of another type. For more information, see X++ Conversion Run-Time Functions. |
Date | Functions that operate on the date data type. For more information, see X++ Date Run-Time Functions. |
Math | Functions that perform mathematical calculations. For more information, see X++ Math Run-Time Functions. |
Reflection | Functions that access the metadata about objects and return other metadata about them. For more information, see X++ Reflection Run-Time Functions. |
Session | Functions that change or report on the context of the current user connection. For more information, see X++ Session Run-Time Functions. |
String | Functions that operate on the str data type. For more information, see X++ String Run-Time Functions. |

Emits a short sound from the speakers on the computer.
void beep()
static void beepExample(Args _args)
{
beep();
}
Creates a globally unique identifier (GUID).
guid newGuid()
A GUID.
The following example creates a GUID.
static void newGuidExample(Args _arg)
{
guid myGuid;
myGuid = newguid();
print strfmt("The GUID is: %1", myGuid);
}
Pauses the execution of the current thread for the specified number of milliseconds.
int sleep(int _duration)
Parameter | Description |
---|---|
_duration | The number of milliseconds to pause. |
The number of milliseconds that the thread actually paused.
static void sleepExample(Args _arg)
{
int seconds = 10;
int i;
i = sleep(seconds*1000);
print "job slept for " + int2str(i/1000) + " seconds";
}
