lineoffset and itemoffset alltogether

[jbv]

Hi all,

Is there a function that returns at the same time the lineoffset
and the itemoffset of a searched string (for instance in the
form 15,4 for "item 4 of line 15") ?
Or is there a (fast) way to do that, instead of checking each
item of the line once the lineoffset has been found ?

Thanks,
JB
