[rules-users] Changing the default character for delimiter in decision tables

Hi All, I wanted to throw to discussion a feature that might be good in Drools. I am basically trying to model a formula evaluator in a decision table. The idea being that a business user directly defines formulas(without having to use Guided Editors in the BRMS or Eclipse, as business users love Excel more than anything else..;)). The thing I am trying to do is the following: Condition Action T:FormulaFact formulaName int salary=t.getSalary(); t.setBenefit($1); Formula1 salary * 100 Formula2 salary * 1000 Everything runs great as Excel simply substitutes the entered string into the function. The problem I face is when I write something like this: Formula3 min(salary,100) The "," here is treated as the delimited of a parameter. So the compiled DRL does not set the string correctly. It would make a rule like Rule FormulaTable_123 When T: FormulaFact(formulaName="Formula1") Then int salary=t.getSalary(); t.setBenefit(min(salary); //Since the words after the , become part of $2 which is not defined. End Is there any-way to declaratively change the Decision Table Parser to not use , for delimiting between parameters and use some other character. I could always write the DT using my character, then compile the DT into DRL and replace my character with ,(I am thinking of using "Colon"), but would it be a good idea to have an Excel or a Property File that can be read by the SpreadSheetCompiler to change the delimited character used by the Parser.
