ITEM1= column number of first response = (required)

Specifies the column position where the response-string begins in your data file record, or the column where the response-string begins in the new record formatted by FORMAT=.

If you have the choice, put the person-identifiers first in each record, and then the item responses with each response taking one column.

 

For comma-separated or tab-separated data files, count the columns in the same way as Excel.
