@rowcode variable stats on 0

Why in a roster linked to a list question @rowcode variable starts in 1 but in a roster linked to a numeric question @rowcode variable starts on 0.

In a roster linked to a list question @rowcode variable may start with any positive value, for example: 238. Avoid making use of the above assumption unless absolutely sure that other restrictions you enforce guarantee you are not getting into troubles.
