The difference with the 35s is that, unlike other models, it tries to compensate for the deletion when you try to replace the deleted line. Example on the 35s:

A001 LBL A
A002 2
A003 3
A004 4
A005 GOTO A003

Now delete line A003 and replace it with 3.333 and see that the program has become this:

A001 LBL A
A002 2
A003 3.333
A004 4
A005 GOTO A004

I don't think any other model screws things up that badly.

Yes, I know that this particular example's problem can be avoided by inserting 3.33 after line A003, then backstepping and deleting A003 ... but that's a workaround for a bad design, IMHO.
