[Coco] Having fun with hacking HDB-DOS

[William Astle]

Actually you can hook the printer output using one of the ram hooks so it should be easy even without having the roms copied to ram. The console out hook is the relevant one I believe. Disk basic already hooks it so you should be able to modify that routine.

Good work Juan, sounds like you're having fun.
How about adding some DW4 commands? 
Redirect PRINT#-2 to the DW4 file printer. It shouldn't be a hard command to patch into and the DW4 routines to pass the data are already present in the hdbdosdw versions. It might be tricky (or improbable) on a Coco 1 or 2 as you may have to move rom to ram, but on a Coco 3 this is already done and patching the CB & ECB roms is easy.

Now the WIDTH command works and drops you in the PMODE 4 screen if the
argument is 51 or 64. WIDTH 32 takes you back to text mode. Also, all
CoCo 3 tokens are recognized. But, of course, all but WIDTH will give
you an error.

Next up: LOCATE. Then... BUTTON? ERR/ERNO/ERLIN?
