IFTE vs ifte...HOME vs CAS

[toshk]

IFTE(({1,2,3,9})<8,{1,7,9,9},{88,89,90,55});//ok at HOME
ifte(({1,2,3,9})<8,{1,7,9,9},{88,89,90,55});//NOT ok CAS, hopefully needs a nudge

{1,2,3,9}<{0,7,9,9};//ok at HOME
if ok at HOME then WHY NOT
IFTE(({1,2,3,9})<{0,7,9,9},{1,7,9,9},{88,89,90,55});//hopefully needs a nudge

{1,2,3,9}<{1,7,9,9};/NOT ok CAS, hopefully needs a nudge
