Re: Parameter value having more than 80 characters
I agree that you might want to split the parameter. Above 80 characters you are really getting to the point where you would be thinking about calling in a note from file or an annotation feature in the model.
¬e_1 would call in full note if that is it's name just as you do with a parameter.
you could also look at restricted parameter sets to pull in complex combinations of information, I've used this for materials supporting information where it can pull in colour vendor and other user defined information in a set of parameters easily selected from a list or sub lists.
If you were to show an example of these long string parameters you might get more from the community.
