I have users I support who have 3 and 4 port data that is saved in generic MDIF files. They may have 1 or more variables in those. I am looking for a way to create a component that would be the equivalent of the currently non-existent symbols named in the subject line. I have already made an enhancement reques some time ago for this, but I do not know the status. I think the difficult part of this is writing all of the equations to read the data and pull it in. One might be able to do this with tremendous pain into S3P_EQN and S4P_EQN symbols.
