>>Yes it works for me wonderfully well and cursors are the way to go to populate comboboxes in scalable applications. You are just making up unrealistic excuses not to use cursors (sys(1104) for example). You are not filling up the arrays with constants hard coded, do you? If you do then hands down, forget I even said cursor.

IIRC next were DS and cursors, where slowdowns could be measured A LOT sooner than with multiple long arrays. After measuring this slowdown (in vfp6) we decided to base the common UC combo/listbox on arrays with an API for feeding in different data.

VFP6 ??? Isn't that the last version handling memory variables much more efficiently? Wasn't that a version where an array could hold 65000 elements at most?
It is interesting that there are so many people in VFP filling up the arrays with hardcoded constants. With hardcoded constants I wouldn't go after cursors either.
