The Gestalt command returns in value a numeric value that denotes the characteristics of your system hardware and software, depending on the selector you pass in selector.
If the requested information is obtained, Gestalt returns 0 in function result; otherwise, it returns the error -5550. If the selector is unknown, Gestalt returns the error -5551.
Important: The Gestalt Manager is part of Mac OS. On Windows, some of the selectors are also implemented, but the usefulness of this command is limited.
For more information about the selectors that you can pass to Gestalt, refer to the Apple Developer documentation related to the Gestalt Manager, available on-line at the following address: http://developer.apple.com/documentation/Carbon/Reference/Gestalt_Manager/index.html
Using version 10.4.11 of Mac OS, the following code displays the alert “You're running system version 0x1049”:
$vlErrCode:=Gestalt("sysv";$vlInfo)
If($vlErrCode=0)
ALERT("You're running system version "+String($vlInfo;"&x"))
End if
