All of your suggestions will work fine, If you are wanting to scan the rest of the table. I can not think of many reason why I would scan the entire table. This is how I would code it:

select table
set order to index
seek msearch
if found()
scan while field=msearch
... do whatever
endscan
endif

this will place your pointer on the starting record and the scan will exit when the match is not longer valid.
