NIPO ODIN Version 5.17
Automatic Syntax Change When Referencing Positions in T-files
When using positions instead of Sample table fields in an S-file, a single run on the NIPO Fieldwork System changes the position references into field references. This happens because the system interprets a T-file as a Sample table internally - all positions within a T-file fall within a corresponding database field.
Example of a stratification file referencing positions in a T-file
286: 1 (6) Males
286: 2 (6) Females
Position 286 and beyond correspond with the field TTExtraData in the sample table. The references are changed accordingly.
Result after a start in the NIPO Fieldwork System
TTExtraData:1 ( 6) Males
TTExtraData:2 ( 6) Females
Note that stratification criteria may not overlap database fields; data may cross two fields if positions are referenced on the border of two fields.
Example of stratification that overlaps Sample table fields
5: 11 (6) region 1 - Males
285: 12 (6) region 1 - Females
Position 285 is the last position of DisplayField4 and position 286 is the first position of ExtraData. As a result, criteria are only checked against the first character of the stratum.
