Problem with editing large sources in VS code Code for i

[Max-Mikkel]

Hi!
We are are struggling with editing large sources in code for i. We have attempted to recreate the issue using a test pgm, containing the same 6 lines of code in repeat:
if var1 = 'A';
var1 = 'B';
endif;
if var1 = 'B';
var1 = 'A';
endif;

When the source becomes longer than around 10 000 to 11 000 lines, the compilation fails with strange compilation errors.
Could this be related a timeout?
the compilation takes around 16 seconds to finish.

Well I can assure you VS Code doesn't have a problem with large files, and the error you're seeing is from the compiler. I have asked a colleague if they have idea about compiler limits with source members.

[Max-Mikkel]

Great! Thanks for you reply Liam. I'll wait then :)

The compiler can handle 100,000's of lines of code. Not sure of the exact limit, but it isn't 10k for certain. However, the IBM Compiler EVENT file (EVEVENTF I think?) may have some issues with excessive site--although I've never heard of any.
Also you say "The editor has a problem" but then refer to "compiler messages".
The free format compile does have a linear routine vs the RPG fixed-format (mostly) line at a time approach. So if you are missing a semi-colon or a closing quote, you could have a learning experience that here-to-date RPG developer haven't commonly seen.

Thank you for the answer Bob. I am quite new to ibm i, so I'm not so steady on which terms to use when.

Having added '**free' to the first line of the source, the source now compiles. We tested with up to 55 000 lines of code, and it works fine.
However, at around 25 000 lines of code or more, the popup that tells me the source is compiling dissappears after a while, and vs code doesn't seem to catch that the source has been compiled. The icon of the source in the arcad-skipper stays red. We can only verify that the source has been compiled by looking at the as400 screen.

What if you click on the bell at the bottom when the notification disappear? Can you get it back?

[Max-Mikkel]

No, I don't get the notification there either, it completely dissappears.

Okay, there may be a timer issue with the message as it can't sit indefinitely. It basically submits your compile and waits for the response file to be loaded. If it takes too long, the message will evaporate automatically.
I only work on my own extensions, but I'll look at the code for i extension and see if that's what's happening. Also I believe they released an updated version or are about to, so maybe try again once that is installed on your PC.
