How did I

… define global variables that could be used with any function and after used by a function F1 record the value of this variable to use like a input in another function?

Hi,

If you mean TF1 functions … from them you can call any functions (known to the interpreter) that takes a numerical value and returns a numerical value. You can create such a function that would record the value you need.

Well I mean functions created by me … not TF1 functions …
