Version type


Version type -> Function result

Parameter	Type	Description
Function result	Longint	Information about the version type (bitfield)

Description

The Version type command returns a numeric value that denotes the type of 4D or 4D Server version that you are running. 4D provides the following predefined constants, found in the 4D Environment theme:

Constant	Type	Value	Comment
64 bit version	Longint	1
Demo version	Longint	0
Merged application	Longint	2	Version is an application merged with 4D Volume Desktop

Note: In current versions of 4D, the demo mode is not available.

Version type returns a value in the form of a bit field; it is necessary to use bitwise operators to interpret it (see the example).

Example

This test lets you run different code depending on whether the version is a merged application or a database opened by 4D / 4D Server:

 If(Version type?? Merged application)

  // We are in a merged application

 Else

  // We are in a database executed by 4D

 End if
