Good that you remind me of this important limitation. Now I just have to make sure I don’t forget it again. :-)

The error message that popped up was something about a "," missing to join the arguments. Would it be possible for NWP to detect if more than one operation is on a line and then display a warning stating that only one operation is allowed? If that is possible then I think we should maybe send a feature request to Nisus Software because the error message I got was not helpful for the user.

This method is indeed new to me. Thanks for writing it down here. I may have picked up the (old) method

$rowNumber = 1
$rowNumber = $rowNumber + 1

in HyperCard a long time ago and in a way it looks logical too.

In this case it figures out what $rowNumber is  then it types the value followed by '.    ' Interpolation is one of those place where you get to cheat the one operation limit a little bit, though here it isn't really necessary.

As always, your ideas are very helpful Philip. Thanks a lot.
