I'm trying to use the interactive function name feature. On emacs lisp
manual it says:
‘a’
A function name (i.e., a symbol satisfying fboundp). Existing,
Completion, Prompt.
So I tried it with a small test code:
(defun testfun1 ()
(message "hello, world!"))
(defun test (abcd)
(interactive "aTheme name: ")
(abcd))
Emacs gives an error saying,
test: Symbol's function definition is void: abcd
I tried to test abcd with fboundp, it returns t. So I'm quite confused
about how to use the 'a' option in interactive.
Any body can give some hints?

Your problem is not with interactive. (abcd) evaluates the function
"abcd", while you want the function contained in the variable
"abcd". Try "apply".
