* The SPSS DATA LIST / BEGIN DATA parser is rather simple minded, the number after the type
* specifier identifies the field width (maximum number of characters to scan)
* It will stop short of that number of characters, honouring quote delimited
* space separated strings, however if the width is too small the remaining data in the current
* line becomes part of the next column. Since we want to restrict this script to ONE scan of
* the data (scan & output at same time), the information needed to construct the
* DATA LIST is held in the $fields array, while the actual data is written to a
* to a temporary location, updating length (size) values in the $fields array as
* the tmp file is generated (uses @fwrite's return value rather than strlen).
* Final output renders $fields to a DATA LIST, and then stitches in the tmp file data.
*
* Optimization opportunities remain in the VALUE LABELS section, which runs a query / column
