Hello Žorvaršur,
Bob is essentially correct. NWP macro doesn't allow more than one operation on a line.
There are a few tricks that allow you to cheat this limit a little bit, but basically that is the limitation.
So in your line:
>> Type text $startNumber+1 & '. '
You are trying to increase $startNumber and concatenate the result with the string '. ', that's two operations. So no go.
Also as Bob said your variable $startNumber is not well named, but more to the point if you write
>> Type text $startNumber+1
you are presumably trying to increase $startNumber, but by doing it that way you lose the increase. Next time you ask for $startNumber it will still be 1, not '+1'. The most "logical" way to increase variables in NWP syntax is to do it like this:
$variable += 1
So, adopting Bob's renaming suggestion, for you case you might write it like this:
> $rowNumber = 1 # this is the 'start number'
> $rowNumber += 1 # increase the row number by 1
> Type text $rowNumber & '. ' # print out the row number followed by a period and 4 spaces
Another way to write the 'Type' line is this
> Type text "$rowNumber. "
By using double quotes you can get interpolation. So NWP first 'figures out' what is in the quotes and then types it. 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.
Just some ideas
