Line support for OnError

[Polo]

What does this feature actually do to the generated asm code ?
I realized I had left that option enabled in my project, when I deleted it the exe was 35kB smaller

I think it adds some indexes to the code so that the faulty command can be shown by the line-number in your source code.

I think at the beginning of each compiled line it puts the line number into a memory location with a simple move operation. It would use less space with a table, but wouldn't be as simple to code.
