I wish to define a function that prompts me more than once: let's call it
`my-function': when I type `M-x my-function', in the echo area I see (just an
example):

 Hi, how are you today?

.  Then I type, e.g., `fine RET', and again it prompts me with:

 I see.  And, what did you do yesterday?

... and so on.  Then I'm going to put some `if... else' conditions over my
possible answers.  Can anybody please provide some hints about how to elisp
this?

Thanks, that works.
I wish to set some ps-print variables in an interactive way, i.e. be prompted
for the value that I want to set.  So, following Barry's hint, I put:


(defun my-manage-ps-font-size ()
  (interactive)
  (let* ((prompt1 (read-from-minibuffer "Font size? "))
         (prompt2 (format "(quote (7 . %s))" prompt1))
         )
  (setq ps-font-size prompt2)
    )
)


, but it seems that the variable's value is put between "" and so it is not
accepted.  I need help in this point.  Thanks to anyone still helping.

Take a look at the documentation of the interactive call, it let's you
read any kind of data from the minibuffer.

(defun my-manage-ps-font-size(size string)
  (interactive "nFont size ? \nsErase all memory ? ")
  (setq ps-font-size (cons 7 size)))

This reads a number and a string.
