Tab in particular

Support for double literals such as 123.

So far, we're just providing access to $0000-$8000. Once the issue of using or not using the kernel has been sorted out, thinking about the memory map would be a good idea. How should we provide access to other banks? Attic RAM? etc

What should we do about the absence of '' in petscii? Backslashes get mapped to the pound symbol, which is at an appropriate spot on the keyboard. Does it make sense to use this as the line comment word? We could make a character set that swaps it for a backslash symbol.

Using the kernel call. FIG used ?TERMINAL for this. I still need to look at how to integrate this without slowing things down horribly

We want this one in partcular so we can rename the autoboot.f file at the end of the bootstrap process

This is needed to get started on unit testing

Should the kernel be used? So far, the implementation has refrained from using anything in the kernel to allow for disabling it and opening up more memory. Can we still turn off the mapping and call everything we want with flat 28-bit calls? That would simplify file handling, let us make use of console i/o, etc.

FIG uses CSP, ?CSP, CSP! for this

Adding support for including files from drives would be very useful

It would be nice to include a decent editor. Most of the available Forth ones are line editors using the block interface. It would be nice to have a visual editor using the file interface. Can we find something existing with an appropriate license?

ACCEPT should have decent command line editing features, but the big priority is DEL

The output when an exception is thrown needs to be cleaned up

INCLUDE should fail with the appropriate exception
