[Coco] Having fun with hacking HDB-DOS

[Bill Pierce]

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?
