Studio 10/11: Referring to list.$remove(0), list.0.$selected

[Doug Easterbrook]

really?

line number ‘0’ has referred to the current line forever ..    Pretty sure it was that way in omnis 7 as well.


as in

do list.$first(ktrue) returns #F
while flag true

   do list.$next(0,ktrue) returns #F
end while


and the documentation says specifically that line zero is the current line



$next(rRow|iRowNumber [,bSelectedOnly=kFalse, bBackwards=kFalse, condition]) sets $line to the next line after the line identified by the first argument. If iRowNumber is zero, processing starts at $line. See $first for definitions of the other parameters


my understanding is that any reference to a list line, where line is 0 is the current line

as in these are all equivalent

calculate list.0.whatever
calculate list.[$list.$line].whatever
calculate list.whatever

do list.$remove()
do list.$remove(0)
do list.$remove([list.$line])
do list.$remove(list.$line)


I’ve always treated 0 and currentliine  the same.  so if that what we all use ….  then breaking the code would be a bad thing to do.   


if it stops working on the desktop, I’d push back.   Just me.
