Source

The Source is the physical location on the raw data record where the reply to the question/variable is stored. In its simplest form, it is a value between 1 and the length of the entire data record. For example at (12 to 61) would refer to character positions 12 to 61 inclusive, a total of 50 characters. As an alternative to specifying the start and finish positions, it is quite acceptable to specify the start position and the length, e.g. at (12 for 50).

It should also be remembered that the Source can refer to the names of other variables in the survey: for example, a question quantity could be the source of a numeric variable.

Be careful when changing the source manually, particularly if you have already entered any case data/replies, as it may invalidate those replies already entered. Wherever possible, allow Snap to change the contents of the source field.
