Creates a Global, or Local, variable with the value specified AND logs it's instantiation to a centralized variable log

Sample Input:
VariableInitialize ( "$$TestVar"; 73 )
Sample Output:
$$TestVar = 73
AND
$$GlobalVarList =
$$GlobalVarList|0
$$TestVar|73


 Then copy & paste into FileMaker Advanced's Edit Custom Function window.

Description:

Requires FileMaker 8 or higher.

Creates a Global, or Local, variable with the value specified AND logs it's instantiation to a centralized variable log, in another tracking global. This tracking global, "$$GlobalVarList", becomes a single centralized location to track and manage variables for the file.

The Data Viewer in FileMaker Advanced can easily be instructed to expose the central tracking global "$$GlobalVarList" thus allowing the developer to view all variables used, or intended to be used, in the file.

A best practice *may* be to use this function to instantiate all variables in a single spot, preferebly an Open Script, rather than at time of need.

Its is possible for local variables to exist outside a script, but their scope is nuanced when they do. If a Local variable (single $) is specified with this custom function it's behavior will follow local variable rules, thus it may behave differently if instantiated within a script or without, as well as return different values with or without, depending .

NOTE: another CF named "VariableDestroyAll" can be used to remove all global variables using the variable log found in "$$GlobalVarList".

Note: these functions are not guaranteed or supported by BrianDunning.com. Please contact the individual developer with any questions or problems.
