(35S) Quick integration

thank you very much for your fast answer.
I know how to code functions in RPN but I do not know how to tell the intergration function of the HP 35s to use the program F for integration instead of an EQN-equation. If I put in lower limit Enter upper limit and then integration it asks for the equation to integrate. Is there a way to tell the calculator to use a program instead of an equation put in in EQN? This would be a little more like with the HP 15 or the HP 42s.
Thanks once more and best regards

In the HP35S when you want to solve or integrate a function other than an equation the "FN=" instruction must be used (up left, in yellow).

So, in case you have a function in, say LBL F, before solving or integrating just press FN=, it will prompt a letter, press F, so the HP35S knows that it will use LBL F when asked to solve or integrate.
