A simple way of having the variable available for all the  processes 
you are running is to include a variable name in the fp config 
file.  For example, MyGlobal
and set the MyGlobal to the value needed for that run.  (MyGlobal=neededvalue)

Then in your processing use x=getenv("MyGlobal") and it will retrieve 
the value into x.
You may need to write a script to change the value of MyGlobal in 
fp\lib\config at the beginning of your batch file.  \fp\lib\config is 
a text file.
