[Coco] Known VCC bugs

I found that my HDIRECT program, fixed and improved from the Rainbow May 
1985 issue will hang when "/P" is loaded and VCC is set up to capture 
the text right on the first line. The very first time I tried it hung.


Robert Gualt while helping me with one of my old boot disks and HDIRECT 
found the same problem just ~ about a week ago.

I cannot say if the problem is with VCC, OS-9 and or NitrOS-9 as I have 
seen the problem with many runs of VCC using various versions of both 
VCC and an OS.

The HDIRECT program and the shell script to load "/P" is named p.s. is 
on SHF888.dsk (ZIP) on my Webspace: ("p.s" will only work if the "/P" 
descriptor is in the image of NitrOS-9 on the VHD)


hdirect                                        91/03/05 12:21       836
p.s                                            12/04/29 14:27        5D

The source for HDIRECT is in my online DoomsDay files set and as soon as 
I get the MB replaced on my backup HTPC I will be working on HDIRECT to 
bring it into the present century and fix other bugs (Huge VHD) and 
adding LHA support if possible.

I have ~ 250 disks to process with HDIRECT so it would be great if this 
problem was solved.

Sample output of HDIRECT is attached.
