DTV layout

A DTV is structured as a CSV file and has 7 columns-

• Name (up to 30 characters)

• Type-

  • S (single-coded)

  • M (multi-coded)

  • I (integer)

  • W (float)

• Size (number of responses)

• Output type -

  • S (single)

  • M (multi-coded, one column per response)

  • F (spreadfield)

  • I (integer)

  • W (float)

• Digits needed to store largest value

• Maximum number of repeats (spreadfield only)

• First data location

The output type must be the same as the input type except that for multi the output type can be M or F.
