PFILE=filename produces an output file containing the information for each person. This file contains 4 heading lines (unless HLINES=N or ROW1HEADING=N), followed by one line for each person containing the following fields and the standard field selection. To change the output-field selection, go to the Output File menu, PFILE=, Field selection, Make default., or POFSFIELDS=.
PFILE=? opens a Browse window
"Status=-2 to -6" means that there are no measurable responses by those persons in this analysis. The persons may be listed in the PFILE= and in Table 18, but all the numbers shown are default values. They have no meaning. Please do not include those persons in summary statistics.
