This is one of the main features of [DynamicMacros](https://github.com/3dcoded/DynamicMacros).

Note that this doesn’t work inside if statements or for loops.

DynamicMacro version of your macro:

```yaml
[gcode_macro run_increment_test_number]
gcode:
   RESPOND TYPE=command MSG="Current Test Number {printer["gcode_macro test_number"].testnumber}"
   increment_test_number

   RESPOND TYPE=command MSG="Test Number after increment {printer["gcode_macro test_number"].testnumber}"

```

> I recently created [DynamicMacros](https://3dcoded.github.io/DynamicMacros/), a way to update simple macros without restarting Klipper. It works by having the “dynamic” macros in a separate file, not included in your printer.cfg. Then, a [dynamicmacros] config section references that file. Whenever a dynamic macro is reloaded with the DYNAMIC\_MACRO command, it reads the provided configuration files and executes the macro. This way, you can edit your macros without restarting Klipper. Currently, dynamic macros support the following: Upd…
