Re: [rules-users] Convert logic to DRL rules

Hi Steven, Yes I thought of that but our business user says this is unacceptable unless I can write a parser to automatically generate all these combinations. The example I use is quite simple. Our business user have quite complex logic expressions (imagin my example plus a lot of parenthesis to build up multiple level logic) already built using Pascal like language and it is not easy to do.
