seq_next

seq_next(lval)
The lval parameter must be an l-value referring to a data item contained immediately in a sequence. The function returns an l-value referring to the following sequence element.
If the l-value does not refer to an existent data item, the data item is not immediately contained in a sequence, or the parameter is the last item in the sequence, an error is returned.
Example:
seq_next(this).x
When this expression is used in a computed item in a table, it accesses the value of the column x in the row following the row, where the computed item is placed.
