Trouble Shooting COPAN/II
In the event that you encounter some problems, this section
may be able to help. Should you continue to be overwhelmed
with confusion, do not hesitate to call us for the answer.
Here are some common questions/comments that frequently
arise when using COPAN/II for the first time:
Unable to load PCAT, LAMCON, COSAN from DOS.
These modules are all have .OVR extensions. This means
that they cannot be run from DOS. To load any .OVR file,
you must first run ACCESS. Only ACCESS can call .OVR
files.
Solution : Load ACCESS from DOS first.
When calling PCAT or LAMCON from ACCESS, DOS prompt
appears.
This usually happens when running a double floppy system as
ACCESS cannot find the .OVR file in the default drive.
After ACCESS is booted, the disk #2 should replace disk #1
as this is where the .OVR files are located. Current
versions will produce a 1001 error message which means the
file was not located. Older versions dump you in DOS.
Solution : Make sure you know where the .OVR files are
located or buy a hard disk.
ACCESS tells me I haven't enough memory
What more need we say. It means that you are a wimp for
one of two reasons. One, you have less than 640K or two,
you use memory resident programs.
Solution : Buy more memory or unload some memory residents.
ACCESS says not enough room for CHAIN or SHELL size.
There are two files that reside on the ACCESS disk (#1)
which help to allocate for COPAN/II .OVR and .COM files.
See page 5 if you haven't already done so.
Solution : Read page 5.
After I type in ACCESS, the cursor just sits there and
blinks at me.
Solution : Press the <RETURN> key.
After I enter ACCESS, the screen blanks out and the disk
just keeps on spinning.
This can happen when the machine that you are running is
not 110% compatible. The TI Professional is an example.
Unfortunately, you're stuck as this problem's solution is
to get a different machine.
Solution #1 : Buy a new machine
The other cause would be that you have an unruly memory
resident program that is not well behaved. Try a 3 finger
reboot to unload the program. If this does not work, then
try playing golf and drinking cold beer.
Solution #2 : Ctrl-Alt-Del or drink beer.
I don't like the colors that I see in COPAN/II. How can I
change them?
Solution : None. WYSIWYG
My machine smokes and makes weird noises when I try to load
ACCESS.
This is common when illegal users try to get into ACCESS.
Solution : Send a check to Parados Technical
Nearly all possible trapping has been built into COPAN/II
to keep nasty DOS exits from occurring however we do not
make any promises. It is possible, with diligent effort,
to create a situation that will make COPAN/II barf like a
dog. Sorry, but we too are human.
If this occurs in ACCESS, PCAT, LAMCON, COSAN, LINER or
CONVERT, you will see a framed box in the center of the
screen telling you that it just barfed. Along with the
message will be an error code that should be used to report
any bugs to us. If you are curious, these are the compiler
error messages that we use to figure out what went wrong.
Here is a partial list of the error codes that could
possibly occur in the above mentioned sections of COPAN/II.
Error Code Possible Meaning
=========== ===========================================
1 Integer Overflow
2 Integer Divide by 0
3 Real Overflow
4 Real Underflow
5 Read divide by 0
10 Byte overflow
17 Too few items in input string
27 Buffer full
28 Buffer empty
36 Overlay too large
39 Overlay data too large
999 Internal error
1001 File not found
1002 Disk full
1003 File not open
1004 File Disappeared/Changed
1005 EOF error
1007 Access denied
1010 File already open
1011 Filename in use
1019 Illegal filename
1023 Illegal drive letter
1026 Shell error
1027 Command.COM not found
There are other error messages but they should not occur.
Actually, we doubt if you will ever see more than one of
these in 10 years of COPANing.
Remember, these are given just for the sake of keeping you
informed. You cannot fix the bug, just avoid it. We will
repair any reported problem as long as you document how it
was produced.
Error Messages for all .COM Files
The other COPAN/II modules such as SecPro, HatMan, SOLVE
and PBS are all written in a different language so
different error codes apply. Again, most of the error
trapping has been designed into the code but with real
effort a fatal DOS exit can be achieved.
If an involuntary DOS exit does occur, make sure to jot
down the error code and the program counter. The program
counter is given as PC=FFFF where FFFF is a hexadecimal
value.
Send them to us and you will usually have the revision
within the week. In a gesture of nice-guyness and in
appreciation for your feedback, we offer a free case of
your favorite beer if you are the first to report the
bug. How many software shops offer that kinda deal?
