I wonder if I can use a gosub inside a function. The reason is that I need to transfer parameters in the function, and that function must call a subroutine, but it didnt work. Can I do that??

You should be able to GOSUB from a function, because it has a return point. It's only like calling another function.

but you may have a variable Scope problem there. Local variables in the function go out of scope when the function ends.

Yes, you can call subroutines from within a function as long as that subroutine is contained in the same .dba file. If you are using a function that has been #INCLUDED (which you should be) then it would look something like this:

FUNCTION my_function()

REPEAT
IF SPACEKEY() = 1 THEN GOSUB space_sub
UNTIL RETURNKEY() = 1

EXITFUNCTION

space_sub:

RETURN

ENDFUNCTION

You have to use an ENDFUNCTION for the true ending of your code block and EXITFUNCTION to leave the function itself. All variables are localized to that code block, though.
