QAFLAGS 23 - What does that do ?

[cyberflow]

Hi all,

Was trying to find information about the "QAFLAGS" variable and I found a procedure to edit autors names and it ask me to set my QAFLAGS at 23.

What does that do ?

QAFLAGS system variable - Quality Assurance flags

Internal system variable with flags for Quality Assurance and testing. The value is stored as a bitcode using the sum of the values of all selected options.

Attention: this is subject to change, and not intended for regular use. Some of these options could have unpredictable or unwanted side-effects.

 

Type:	Short
Saved in:	Registry
Range:	0 to 32767
Default value:	0
Possible options:	1: Red device: no low quality draw 2: No pause during text screen listings 4: No 'alert' dialogs (text display instead) 8: Have Warnings act as Errors and stop scripts 16: Minimal audit report 32: Disable window recreation on switch between 2d and rendered visual styles. 64: Enable various performance measurements printed as info prompts 128: Parallel vectorization: EnableSchedulerLogOutput 256: Cmd message enable 512: Dcl take screenshot 1024: Print time on statusbar 2048: No crash dump file 4096: Create assert log file 8192: Create RED files during rendering 16384: Parallel vectorization performance measurement

Well chatGPT is pretty powerfull for simple questions, here's the answer : 

In AutoCAD, the `QAFLAGS` system variable is used for enabling and controlling certain diagnostic and debugging features. When `QAFLAGS` is set to a specific value, it activates different features for testing or debugging purposes.

Setting `QAFLAGS` to `23` (or `0x17` in hexadecimal) enables several specific features. Here's a breakdown of what these flags represent:

1. **Bit 0 (1)**: Enables diagnostics logging.
2. **Bit 1 (2)**: Enables extended debugging information.
3. **Bit 2 (4)**: Enables the display of detailed performance information.
4. **Bit 3 (8)**: Activates additional user interface elements for debugging.
5. **Bit 4 (16)**: Enables logging of additional internal system events.

So, when you set `QAFLAGS` to `23`, it enables all the above features:

- **Diagnostics logging**
- **Extended debugging information**
- **Detailed performance information**
- **Additional UI elements for debugging**
- **Logging of additional internal system events**

These settings are typically used by developers or advanced users who need to diagnose issues or understand the internal workings of AutoCAD more deeply. It is generally not recommended to change this variable unless you are troubleshooting specific problems or developing custom applications for AutoCAD.

Thx @pendean  !

To note that when changing the flags we need to restart the software so we can use certain functions in debuging or else the commands aren't visible if the software isn't rebooted.

As great as Chat can be, it looks like its response has an issue. To get to QAFLAGS 23, it should be 16 + 4 + 2 +1 = 23
It does not use the 4th bit (8) to Activate additional user interface elements for debugging.

Hi @matt.worland,

You are right ! The (8) isn't used in the 23 !

Excellent remark !
