[Coco] Having fun with hacking HDB-DOS

Sat Apr 19 22:06:55 EDT 2014

Hi Juan!
That sounds Great!  Keep up the great work!  You definitely have a fan here.
With your updates to HDB-DOS, you just might get me to do some work on the
Basic side of things.  Now I can print Directories again!  I love the
updates you've tried to do thus far.  Take care my friend.
Kip

Still avoiding the complications of IDE, so I took on virtualizing printing.
Now I can print to DW's virtual printer! But there's a catch.

LLIST prints all lines without newlines between then. Also, I have to force
a flush with PRINT#-2 in order to even that to show up. Well, at least
PRINT#-2 works as advertised. I set it up so whenever a CR, LF or FF
character is printed, I send a flush command. The text shows up in the
cocoprints directory as it should.

Examining the LLIST code (which is LIST with DEVNUM set as -2) I see it has
the brilliant idea of not using CR or LF, but just outputs spaces until the
"device position" reaches the "device width".

OH NOW I GET IT. I should be updating the device position every time I
output a character. Excuse me.
