In many cases machines have boolean parameters. This means
that their parameters may have only 2 values; 0 (usually OFF) or 1 (usually ON).
When you see a column in a Aldrin pattern which is only 1 period wide, this is
the case. These 1 dot columns will accept only the two values 0 or 1.
Enter these values from your keyboard just as you would in any other parameter
column.
