On Monday night I had an idea about creating a Stack UDF as I hadn't seen one on the Forums, but then I did a little searching and came across this. Not to be dismayed, I still created my version as I had already planned how I was going to implement it and decrease the number of redims.   Enjoy. Global Const $STACK_GUID = '736DBB18-0DF3-11E4-807A-B46DECBA0006' Global Enum $STACK_COUNT, $STACK_ID, $STACK_INDEX, $STACK_UBOUND, $STACK_MAX #Region Example #include <Array.au3> Example() Fun
