Gunner,
Not sure about that one. You might be able to guestimate the aprox proper location of of the scroll bar (or whatever it is) by the index expression.
For instance, if the tag is upper(lastname)
lscrollbarloc=ltotalscrollbarlength*;
((asc(upper(lastname))-64)*26+; &&A-Z position of first character
asc(substr(upper(lastname),2))-64); &&A-Z position of 2nd character
/676 &&&value for last position ZZ
This should give you a pretty good representation of where someone is. Your index expression may require a differn't formula.
