Global Variable Initialization in Startup Process
Add a Python/Tcl function which defines a global variable with initial value, so that the user can call the function in Startup Python/Tcl script.

The underlying FME Engine can give an initial value to a GlobalVariable so it would seem we could find a way to do this.
You can currently do this manually by declaring a global object e.g. in the startup Python script. However, if your workspace contains a Python-based transformer (I'm looking at you, StatisticsCalculator!), then the Python interpreter gets re-initialized when the first feature hits it, and your global objects are all gone...
Having fmeobjects access to the variables in the VariableSetter/VariableRetriever would be nice.
@david_r, thanks for the tip. I sometimes use Python global variables, but it doesn't have compatibility with FME global variable, and also my loving Tcl doesn't support workspace-wide global variable unfortunately. My dream is to use a workspace-wide global variable which is compatible among all of FME, Python and Tcl ;)
It reminded me. You can fetch a global variable value in a PythonCaller.
v = feature.performFunction('@GlobalVariable(aVariable)')
Tcl has also a built-in function called "FME_Execute" to execute an FME Function. FYI.
