4D v13.4

Application version


Application version {( buildNum {; *} )} -> Function result

Parameter	Type	Description
buildNum	Longint	Build number
*	Operator	Long version number if passed, otherwise Short version number
Function result	String	Version number encoded string

Description

The Application version command returns an encoded string value that expresses the version number of the 4D environment you are running.

- If you do not pass the optional * parameter, a 4-character string is returned, formatted as follows:

Characters	Description
1-2	Version number
3	Update number
4	Revision number

Example: The string "0600" stands for version 6.0.0.

- If you pass the optional * parameter, an 8-character string is returned, formatted as follows:

Characters	Description
1	"F" denotes a final version
	"B" denotes a beta version
	Other characters denote an 4D internal version
2-3-4	Internal 4D compilation number
5-6	Version number
7	Update number
8	Revision number

Example: The string "B0120602" would stand for the Beta 12 of version 6.0.2.

The Application version command can return additional information in the optional buildNum parameter: the build number of the current version of the 4D application. This is an internal compilation number that can be used for versioning or when contacting the 4D Technical Services department.

Note: In the case of applications that are compiled and merged with 4D Volume License, the build number returned is not significant. In this context, version information is managed by the developer.

Example 1

This example displays the 4D environment version number:

 $vs4Dversion:=Application version

 ALERT("You are using the version "+String(Num(Substring($vs4Dversion;1;2)))+"."+

 $vs4Dversion≤3≥+"."+$vs4Dversion≤4≥)

Example 2

This example tests to verify that you are using a final version:

 If(Substring(Application version(*);1;1)#"F")

    ALERT("Please make sure you are using a Final Production version of 4D with this database!")

    QUIT 4D

 End if
