Can't step program?

[HazeSystem]

It seems that no matter what I do, there's no way to pause a program and step through it in the debugger. I've only been able to step through a program that has a bug that causes execution to halt.

There's a device you can write to that triggers the debugger. I forgot what it is.

Ahh okay, it's writing a non-zero value to .System/debug (#0e). Could you add that to the Readme perhaps? :)

[randrew]

It's in the Varvara document, sorta. Maybe @neauoire could change the Varvara documentation so that it says "invokes some emulator-specific debug function" or something?

Ah! yeah I went and made it clearer :) #010e DEO is indeed the way to do this.

Sending a non-null byte to the 0x0e port will print the content of the stacks or pause the evaluation if the emulator includes a step-debugger, sending a non-null byte to the 0x0f port will terminate the application.
