I think this should work, or at least it is close to it.
Names Default To Here( 1 );
dt = Current Data Table();
colList = dt << get column names( string );
For( i = 1, i <= N Items( colList ), i++,
If( Left( colList[i], 14 ) == "NAME [US] 1999",
Column( dt, colList[i] ) << set name( "AMERICA " ||
Word( -1, colList[i], " " ) )
)
);
