Here's your answer from ChatGPT

Short answer: No. There still isn't a native setting in the Microsoft Access VBA editor that lets you display persistent line numbers in the code window like you see in other IDEs (e.g., Visual Studio). The built-in Visual Basic for Applications environment simply doesn't support that feature.

Here's how it actually works today:

The VBA editor does not show line numbers down the left margin. There's no option in Tools  Options to turn them on like in modern IDEs.

With the standard toolbar you can see the current cursor's line and column in the status display, but that's it - no permanent line numbering.

Workarounds people use:

External tools/add-ins (e.g., MZ-Tools or other VBA utilities) can overlay or inject line numbers in your modules, or at least help with navigation and error tracing. These tools actually modify or annotate your code rather than enabling a native editor feature.

Manual numbering or code modules: In old BASIC/VB fashion some developers insert numeric labels (e.g., 10, 20, 30:) manually or with a script to support the Erl function in error handlers - but this is purely a coding convention and not a live editor feature.

Bottom line: if you want real on-screen line numbers in the Access VBA IDE, you still need a third-party add-in or a custom macro to stick them in - Access/VBA itself doesn't provide that feature out of the box.

You just have to put them in manually.  The compiler will ignore them.  Line numbers are generally considered obsolete.

You also have to manage them manually.  If you reference a duplicate line number with something like a GOTO statement, the compiler will complain.

Hi Mubeezi long time no speak, hope you're well :-)

I think https://www.mztools.com/v8/features.aspx does it. Maybe other tools do too.
I'm sure I read an article on it recently just need to find the link, let me circle back when I find it.

I'm just curious what you need them for. I've been developing with VBA for like 30 years now, and I've never needed line numbers.

Mubeezi here's a little gift for you:

Add Line Numbers in the Code Vault.

And since you've been a long-time customer since 2010, I gave you a month of Gold membership for free so you can see it.

The Line and Column is indicated at the top if you need it for reference.
