At Dim the created Paper is like a Blue Print that has some empty spaces not yet filled in. A String is a bit tricky. The Blue Print code line Paper in the Pigeon Hole will allow to note the string Length and an Initial start memory Location. This Location well have to change frequently as strings of different length are assigned. Instructions will tell how to do this.

Simple Array Bubble Sort Example working similar to VBA Range.Sort with one Key1:=
A further modification is done to the previous routines so that values that can be seen as numbers are compared as numbers in sorting. This is done so that, for example, a number like 46 would be seen as greater than 7. In previous routines, these would be compared as text values of "46" and "7". In a text comparison, the sort is done initially on the first character so that "4" would be seen as less that "7". ( The second character, "6", in this exampple is not used. A second character would only be used to sort if we had two values such as "46" and "49". In such an example VBA would place "49" above "46" for a text comparison
We find that the VBA Range.Sort Method sees text as text and numbers typically as numbers , and the final purpose of the routines we are developing in the associated main forum Thread is to do somethhing similar to the VBA Range.Sort Method

Initial Function for Simple Bubble Sort
In the routines
Sub TestieSimpleArraySort5() and Function SimpleArraySort5(______) As Variant
below , the main difference over the previous routines is the extra As Variant at the signature line, and finally a code line just before End Function of SimpleArraySort5 = arsRef()
In the testieing routine, we use codes line of this form in the conventional way in which a function is typically used.
_ arrTS() = SimpleArraySort5(arrTS(), _ 0 _ )
But we note that by virtue of using ByRef a simple call would surfice
_Call SimpleArraySort5(arrTS(), _ 0 _ )
Note: we have added an extra testing code section '2b)
In this extra section we fill a new array, arrDesc() , with the sorted array in Descending order. We use for demo purposes a typical function using code line
_ arrDesc() = SimpleArraySort5(arrTS(), 2136)
Correspondingly we have a demo output giving code line
_ RngToSort.Offset(0, RngToSort.Columns.Count * 3).Value = arrDesc()
We note further, that this is somewhat redundant. This is because the code part SimpleArraySort5(arrTS(), 2136) has the effect of re filling arrTS() with the newly sorted array by virtue of the use of ByRef in the signature line of the Function
We could therefore simply use a code line like _..
_Call SimpleArraySort5(arrTS(), 357)
_.. followed by an demo output giving line of
_ RngToSort.Offset(0, RngToSort.Columns.Count * 3).Value = arrTS()
