Edit July-24 2008 :
v1.1 > Replace "Num" by "CLNum"
[please, do not used "CLNum" in your calculation with Let() ]
-----------------------------------------

it is not a recursive function
For data processing, customized lists, reverse lists.

-----------------------------------------

- Build a descending list [for an Ascending List, used CustomList ()] - http://www.briandunning.com/cf/868

- Build any list based on all Native or Custom Functions involving a 'Number' value as a parameter, such as :
Left(), Middle(), GetValue(), GetRepetitionNumber (), GetNthRecord(), GetLayoutObjectAttribute () ...
ex : - CustomList_BottomUp ( Get ( FoundCount ) ; 1 ; "GetNthRecord ( FirstName ; [n] )" )
will return James¶Henry¶Susan if your foundset has 3 records.

- Build any range based on Dates, Times, TimeStamps, and obviously Numbers
ex : CustomList_BottomUp ( 5 ; 1 ; "GetAsDate ( StartingDate ) + [n]" )
will return a range of 5 dates starting from the specified StartingDate

The 'Function' Parameter is nothing else than a litteral calculation expression.
Therefore, CustomList_BottomUp allows for any filtering or parsing process based on any condition you may need.
ex : CustomList_BottomUp ( 100 ; 10 ; "Let ( [ Value = GetValue ( MyList ; [n] ) ] ; Case ( PatternCount ( Value ; "X" ) ; Value ))" )
will parse any value containing a "X" in the 'MyList' chain, in between the 100th and the 10th values.
