users own permanent global functions?

hi, lets say i have the following 3 functions:

//get size of object, width*height
//pass maxobject.rect to argument
function getsizeo(array) {
x=array[2];
y=array[3];
return x*y;
}

//get x dimension of object
//pass maxobject.rect to argument
function getxdimo(array) {
return array[2];
}

//get y dimension of object
//pass maxobject.rect to argument
function getydimo(array) {
return array[3];
}

which would return various parameters from the max object rect function. say i then quit max, then start again on the next day, but this time from new. is it possible for me to make these previously defined functions available to a completely new js script with out having to implement them again? such as every time i want to use them from now to eternity i can just write yval=getydimo(namedobject.rect) without needing the implementation somewhere in my new max patch? hope this makes sense, maybe universal is the word i want
cheers,,
