OK. I see. What you want to do will work fine. You can even delete the second line of your program (the "A").

You can't key it in because the structure is not allowed. Symbolic evaluations are not allowed within programs. They were allowed in version 11 and earlier, but not any more. Even then, the only way to create them was cut and paste.

Thanks for the bad news.......

Strange enough, it seems to be working for this one "Symbolic Only" Ei function (attached), using the cut&paste method....Are there any exceptions to the "Not Allowed" rule?

Do you see any downside using the program as is?

Thank you.

I am a little surprised it lets you do that. So it seems you can evaluate a symbolic expression inside a program, but you cannot subsequently use the result of that evaluation in the program (which arguably makes it pointless evaluating it in the first place!). Inn the attached worksheet the last two programs work in MC11, but not in later versions.
