Is there a limit of characters in the document JavaScripts window?

Question

Hi,
I have several functions with huge arrays of data linked to a button field. All works fine if everything is declared in the document scripts and if the array is not too big. Once I try to insert a very huge array in the document script I receive the message "text is too large to be displayed in this dialogue". Why is so? Is there a limit of characters in the document script window?
I am therefore trying to set up all arrays and functions in a separate javascript file and then embedded it into the 3d annotation. But when I do so,I loose the link to the button field action.
As an example I have embedded in the 3d annotation:
global.X= [[10,20,30,40],[5,15,25,35],[7,17,27,37]];
function Update(n) {
     getAnnots3D(0)[0].activated = true;
     var a = global.X[0][n];
     var b = global.X[1][n];
     var c = global.X[2][n];
     var Mycamera = this.getAnnots3D(0)[0].context3D.scene.cameras.getByIndex(0);
     Mycamera.position.set(a,b,c);
     camera_1.roll = 0;
and then I add in the button field Mouse Up action:
Update(3);
but nothing happens (while if the same script is in the document level script it works). I am probably missing the link between the embedded function and the button field? (either at host/doc/app level..)
many thanks for the help!

Your script contexts are messed up.
That script is expecting to be run at the document level because it's collecting a reference to the 3D API (via getAnnots3D). You also have an undeclared variable (camera_1).
If you want it to work as a 3D embedded script (not sure why) then you will need to remove the reference to "getAnnots3D.context3D" from the function, so you'd simply say
var Mycamera = .scene.cameras.getByIndex(0);
There's no point in using the first line of the function to activate the API, as the function wouldn't exist until it was active.
Your button will then need to target the function with a reference, so it'd be getAnnots3D(0)[0].context3D.Update(3); (you will also want to put the activation command on the button's event)
