QUESTIONS AND ANSWERS
From: Shaffer 50312
I have some questions concerning the
Commodore wedge that you discussed in
your DOS and Don'ts Part 28 and also
in the DOSPLUS program in issue #12.
In the Jan. '84 issue of Creative
Computing in the Commodore Port
feature, one of the commands discussed
was @UI, for resetting the DOS. I was
just curious why it wasn't mentioned
in the DOS and Don'ts article, and
I wanted to know if it is the same
as the @* command in DOSPLUS. Lastly,
concerning the @U or UN-NEW in DOSPLUS
DOSPLUS, what does SYS64738 do?

>SYS64738 begins a routine to do a

I have recently purcased 5 of your
LOADSTAR disks to try so I can decide
if I want to subscribe. On disk 11 it
says there are six sprite files. How
do I load them?

How can I change the colors on the
House Inventory program? I cannot read
the screen with the program as it is
on the disk.

Your instructions for making a
feed-back disk are to insert a 'blank'
disk to proceed further. All reference
is to a 'blank' disk. Since you do not
refer to a 'formatted' disk, it was my
asumption that you really meant a
'blank' disk that would, among other
things, be formatted during the
process. But this is not so! The
program does not format a completely
'blank' disk. Apparently the program
looks for a header, and if it finds
none it just keeps looking.
Since I am not overly loaded with
smarts, I customarily follow computer
instructions literally before I try to
interpret them (computers can be picky
about this).
Obviously, I figured out that which
was not overly apparent. It is just
just possible that you may be missing
some feedback from others who make
these same assumptions.
Most neophytes become somewhat
frustrated when a computer program
does not do what they thought it
would, even if they did make the wrong
assumption....which probably gave
birth to the term 'user friendly'.
It might be to your advantage to
exchange the word 'formatted' for the
word 'blank' in this program, even if
you don't want to make the minor
change necessary to format a 'blank'
disk.
