Use of Functions

[PhilOfPerth]

Functions can be used inside functions so you can do multiple functions in a single line of code.

A sub has to be run and the results run some place else.

Look at all the built in functions we use in the QB64 language, for instance LEN(myString$) or Mid$.

You can do this:

Function LastLetter$(mystring$)
LastLetter$ = Mid$(mystring$, Len(mystring$), 1)
End Function

Now LastLetter$ might be used in another function or sub or by main code.

I can see we may use several arguments in a Function, but  does a function always only return one value?
With a Sub I can change several variables at the same time.
