Syntax to copy multiple cues in a list

Hi,
Can someone please post the command line required to copy a range of cues on a given list to the same list so for example.
List 13 copy cue 4>6 list 13 cue 7>9.

Is this correct or am i missing something in the command line or is the syntax wrong.
Using an IPC latest build 1949,

thanks Cormac
