Feb 2009 -- Due to time pressures, the ongoing development of 'rope' has been suspended temporarily.

ROPE Language Reference - "move"

The "move" action advances the $offset by the specified number of bytes, hence moving forwards (for possitive values) or backwards (for negative ones) within the packet being inspected.

So:

4 move            # moves forwards 4 bytes
move( 4 )         # ditto

-8 move           # moves backwards 8 bytes
move( -8 )        # ditto
