Nadya,

Not sure if I understood you, but instead of adding the items based in their TabOrder in the form, you can order the collection, something like this:

Add a command button and put in the click()

loTabObjects	= Createobject('Collection')

with loTabObjects as Collection 
	for each loObject in thisform.Objects
		if Pemstatus(Evaluate("thisform." + loObject.Name), 'TabIndex', 5)
			.add(loObject, Transform(loObject.TabIndex, '@L 999999999_'))
		endif
	endfor
	.KeySort	= 2
endwith

activate screen
for each loObject in loTabObjects
	with loObject
		? .Name, .TabIndex
	endwith
endfor

Does this help?
