System variables
QDI/DRS DSC sets up some
System variables to hold the information stored for each respondent in the standard .
drs variables. These variables are recorded in the first three lines relating to a respondent in the .
drs file. The first of these lines always starts with
##recstart, the second with
##ac, and the third with
##init. Here is an example:
##recstart 20
##ac rodriguez-u 000830 174522 174908 346 967675522 967675748
##init 20 1 0 0 1 3 2 255 0 54235
