Example 1: Columns 3 and 4 of the item label (between &END and END LABELS) contains content-area code:
DPF = $S3E4 ; start in column 3 and end in column 4 of item label
tfile=*
31 ; Table 31 is DPF Table (or use Output Tables menu)
*
Example 2: Columns 3 of the item label contains a content code. Column 5-6 have a complexity code. Two independent DIF analyses are needed:
DPF = *
$S3W1 ; content analysis
$S5W2 ; complexity
*
tfile=*
31 ; Table 31 is DPF Table (or use Output Tables menu)
