Description
The QR Get drop column command returns a value depending on where the drop was performed:
- if the value is negative, it indicates a column number (i.e., -3 if the the drop was performed on column number 3)
- if the value is positive, it indicates that the drop was performed on a separator preceding the column (i.e., 3 if the drop was performed after column 2). Keep in mind that the drop does not have to take place before an existing column.
If you pass an invalid area number, the error -9850 will be generated.
