Negavtive Rank in the FirstSortedValue

[#1]

I am trying to get the next and the previous value to the firstsortedvalue.

In the below expression, can I give a -ve number (<-1) to the rank to get the next value. If not, how do I get the next value. I can not have it in the script as the value is dynamic.

FirstSortedValue([{SetExpression}] [DISTINCT] [TOTAL [<fld {,fld}>]] value, sort_weight [,rank])

TIA.
