Thanks Guys for the INFO. Mucho appreciated. I think i was not paying 
attention in my assembly language class??:)

RE: lingo-l Comparing Multiple Lists with One List

[Ike Eisenhauer]

Well basically because OR is a boolean operation and doesn't understand
multiple iterative parameterization (fancy word for what you are trying to
give it), if I understand what you are trying to get at.  Try this instead:

--IN Movie Script
on startMovie
global gListStorage, gListStorage1
  gListStorage = [scn 1a, scn 2a]
  gListStorage1 = [scn 1b, scn 2b]
end
Where gFrameClips = [scn 1a, scn 2a]
on mouseUP
if ((gListStorage = gFrameClips) OR (gListStorage1 = gFrameClips)) then
go scn 3a
  else if ((gListStorage1 = gFrameClips1) OR (gListStorage = gFrameClips1))
then
go scn 3b
  end if
end

Hope that helps,

Ike Eisenhauer

Hi All,

I am comparing Multiple lists with one list with the OR statement. For
somereason it does not work. When there is no OR statement it works.
What am i doing wrong.

--IN Movie Script
on startMovie
global gListStorage, gListStorage1
  gListStorage = [scn 1a, scn 2a]
  gListStorage1 = [scn 1b, scn 2b]
end
Where gFrameClips = [scn 1a, scn 2a]
on mouseUP
if (gListStorage OR gListStorage1) = gFrameClips then
go scn 3a
  else if (gListStorage1 OR gListStorage) = gFrameClips1 then
go scn 3b
  end if
end

Re: lingo-l Comparing Multiple Lists with One List

[Bill Numerick]

gFrameClips = [scn 1a, scn 2a]
on mouseUP
if (gListStorage OR gListStorage1) = gFrameClips then
go scn 3a
  else if (gListStorage1 OR gListStorage) = gFrameClips1 then
go scn 3b
  end if
end

As far as I know it has to be like this

if (gListStorage  = gFrameClips) OR (gListStorage1 = gFrameClips) then

HTH

Re: lingo-l Comparing Multiple Lists with One List

I am comparing Multiple lists with one list with the OR statement.
if (gListStorage OR gListStorage1) = gFrameClips then

Here's your problem. You're doing a boolean OR of gListStorage and 
gListStorage1, then comparing that with gFrameClips.

It should work if you do it like this:

if (gListStorage = gFrameClips) OR (gListStorage1 = gFrameClips)

Booleans can be tricky. It might be easier to understand if we start with 
binary numbers and bitwise boolean operators:

0010 OR 0001 = 0011

In most languages, boolean operators are first in the order of precedence. 
Plus, you've added parentheses to further enforce that order.

With our binary example, consider the following two statements:

if (0010 OR 0001) = 0001

will evaluate to false because the expression within the parentheses is 
evaluated first. So, what actually happens is:
1. (0010 OR 0001) evaluates to 0011
2. 0011 = 0001 evaluates to false.

On the other hand, rearranging the parentheses:

if (0010 = 0001) OR (0001 = 0001)

if (0010 = 0001) evaluates to FALSE, but

(0001 = 0001) evaluates to TRUE

so your OR comparison works.

HTH. Maybe I've done too much assembly language programming.

Cordially,

Kerry Thompson

Re: lingo-l Comparing Multiple Lists with One List

[Colin Holgate]

on mouseUP
if (gListStorage OR gListStorage1) = gFrameClips then
go scn 3a
  else if (gListStorage1 OR gListStorage) = gFrameClips1 then
go scn 3b
  end if
end

You need to test both:

if ((gListStorage = gFrameClips) or ( gListStorage1 = gFrameClips)) then
