Fred, to make it complete: besides using an ABtool table 
also the use of persistent or global variables, environment 
variables, and finally reading it from an ordinary text file 
via ABtool is possible too. The right choice of all these
possibilities ABtool offers depends of course on individual 
preferences (ie. some, here minimal, programming is necessary 
with ABtool).
And, these parameters could be updated/recalculated 
with another (or same) script too, again with the help of ABtool.
