Writing a lingo script from an Interface

Question

Hi all,
I wonder if there is any way to write a Lingo Script (movie)
from scratch from an interface in director. In particular, I want
to create an interface where when i will input a question + an
answer and press the button next a particular line of code will be
wirtten. For example:
On answergeneration
if the text of member ("Question") = "Yes" then
do this
end
Is there any way to write the code from scratch by simply
using the next button?
Many thnaks

If you never erase that member, you'll end up with multiple
unnamed script
members. If you want to use the same script member, don't
create it in code.
Just create it once during authoring, give it a name, and
refer to it by that
member name.

All lingo must be in a handler defined with the 'on' and
'end' keywords.
Setting the scriptText of a script member to a single line
just won't work
since there's no handler name to execute. You would need to
create the entire
script, including the on handlerName, the lines of code, and
the 'end' with
RETURNs in appropriate places. Then you would execute it in a
line of code as
(from this example) handlerName. Something like the following
where I've
created a handler named doIt
global scriptname -- global since I don't know where you're
getting it
on mouseUp me
scr = "on doIt" &RETURN
scr = scr &scriptname &".hap" &RETURN
scr = scr &"end"
member("dynamicScript").scriptText = scr
doIt
end
That seems like a very convoluted system, though there may be
a good reason
for it. What if a user enters a number representing a handler
that doesn't
exist? Say, 2147483647. Do you have a handler (object?) named
2147483647.hap?

I'm really not catching the concept here. You mention the
text of member
script containing the text of member "current_script" equal
to a supposed
variable enclosed in quotes (thus making it a string, not a
variable) and
wrapped in ampersands - which you later refer to as a
variable named
scriptname without ampersands. All somehow related to the new
script
member(customscript). *I am thoroughly confused*.
What is member("current_script")?
How does the user input the value for scriptname? Do they
type a 1, 2, 77, or
whatever into a #field or #text member? Then a mouse click is
supposed to
execute a handler in dialog (is dialog a MIAW?) named as
1.hap, 2.hap, ...
according to what they typed?
Where does &scriptname& come into the picture? Is it
related any of the
above?
Are you sure you need to use self-modifying code here? Maybe
you can use
parameters instead.
-- PSEUDO CODE FOLLOWS
-- movie script in (I assume) window "dialog"
on hap (aValue)
case aValue of
1: doThis
2: doThat
3: doOther
otherWise
alert("Please provide a value")
end case
end
-- behavior script
on mouseUp me
aVal = <get the user's input value from somewhere?>
tell window("dialog") to hap(aVal)
end
Or are you incrementing a variable for each mouse click on
the "next" buton?
First is supposed to execute 1.hap, 2nd time it executes
2.hap, etc.
If so, still no need for modifying code at run-time. Assuming
a similar movie
script shown above:
property pClicks
on mouseUp me
pClicks = pClicks + 1
tell window("dialog") to hap(pClicks)
end
Let me know if I'm way off base here. If so, please explain
in more details
what you really want to happen.
