multiple variables from a return

Can I do something like this:

string st_textureStore;
integer in_gridType;
interger in_currentSheet;

getTextureGrid(st_textureStore, in_gridType, in_currentSheet)
{
in_currentSheet = (in_currentSheet+1);
.........
return (st_textureStore,in_gridType,in_gridType);
}

default
touch_start(integer touch_num)
{
.......
getTextureGrid(, , ;
// I would now have a new value for the three variables:
// string st_textureStore
// integer in_gridType
// interger in_currentSheet

It looks like you want to use global variables anyway, so why return the values also? Anyway, you can return lists, and extract the list's elements after getting it back. Like:

list func1()
{
   return [ 1, "my dog", 3.0 ];
}

func2()
{
   list returnedList = func1();
   integer elem1 = llList2Integer(returnedList, 0);
   string elem2 = llList2String(returnedList, 1);
   float elem3 = llList2Float(returnedList, 2);
}

thanks for that
