Description

Stores a named variable that can be retrieved later using FM.VariableGet.
Unlike the variables that were introduced in FileMaker 8 these variables are not limited to the File or Script. In other words they can be retrieved from any file in the system regardless of where they were declared. All values are stored in their native data types (up to version 4.4 only text).

Use FM.VariableClear to clear the variables or FM.VariableClearAll to clear them all. FM.VariableList returns list of all defined variables.

On server, variables are shared by all users connected to the same server and will persist between sessions. So, for example, all Web Direct users will have the same set of global variables set via the plugin. You can optionally prefix variables with a user ID/Name to make them per-user unique. Variables will stay in memory until explicitly released; or the process quits. If you'd like to share data between multiple processes (e.g. Web Direct, Data API and Server Scripting), please use the SharedMemory functions like SharedMemory.SetValue.
