I couldnt get that to work as advertised.

Shouldn't it be something like this

// DateAsText ( TheDate ; Format )
// Supports YYYY and YY, MM and M ; DD and D formats
// separators should be set in Format (use a value list)
// not recursive

Let
(
[
TheYear = Right ( Year ( TheDate ) ; PatternCount (Format ; "Y") ) ;

TheMonth = Case ( Month ( thedate ) ≤ 9 ; Right ( "00" & Month ( thedate ) ; PatternCount ( Format ; "M" ) ) ; Month ( thedate ) ) ;

TheDay = Case ( Day ( thedate ) ≤ 9 ; Right ( "00" & Day ( thedate ) ; PatternCount ( Format ; "D" )) ; Day ( thedate ) ) ;

Simplified = Substitute ( Format ; ["YY" ; "Y" ] ; ["YY" ; "Y" ] ; ["MM" ; "M" ] ; ["DD" ; "D" ] )

] ;

Substitute ( Simplified ; [ "Y" ; TheYear ] ; [ "M" ; TheMonth ] ; [ "D" ; TheDay ] )
)

Sorry for returning to this so late. I accidentally pasted the wrong code initially. It should work now.
