Re: Error trapping on TI-85? (fwd)
No, actual it takes time to program the error trapping into the code of
the program, being part of the program it increases the size of the
actual program, and lastly the error trapping routines use CPU cycles to
read through the data that has been enter to see if it is legal. Each
data type to be input will have to have it own error trapping routines,
which will use physical memory to store.
I am not an Comp Sci instructor. I am a certified computer Enigneer. I
assist personnel on a daily basis with there computer problems.
I see a problem, are you trying to sell Ti-85 to an organization for use a
s personnel digital assistants with the Graph-link as a way to back up the
data entered into a TI-85 up to a PC?
You might have a problem. A TI-85 has 28Kilobytes of user space for
programs and data. If you could find someone to write this code with
error trapping, it would be so big as to leave little space for much
stored data.....
The TI-85 is a Calcualtor! People by them to check there Math, Stat,
Engineering, and Physics Homework! Not a substite for a Laptop computer.

Your arguments are specious, I'm afraid.
The TRS-80 series had an "ON ERROR GOTO" statement in its BASIC
interpreter 15 years ago.
And if you are in fact a computer science teacher, you already know that
error trapping consumes no CPU cycles or space in one's program unless it
is used -- in which case it is often vital.
I am preparing to return the TI-85 we purchased for testing. TI has not
responded with any information or help, and TI's support line refused to
put me directly in touch with an executive with product management
responsibility. Instead, they took a number and never returned the call.
This behavior is on a par with the poor marketing and customer relations
skills TI exhibited at the time when the TRS-80 was manufactured. I'd hoped
they had improved since that time.
Unless TI returns my call by the close of business today, they will lose my
client as a customer. This will means that they've blown a chance to bid
on a contract for at least 1,000 units -- and probably several times that
in the future. Them's big bucks.
Fortunately, it looks as if both Casio and Franklin will be more
cooperative and responsive.

But I would like to point the ti-8x serials have the same CPU chip that
was in circa 1980 TRS-80, in my computer day back then I don;t remeber
error check as a major concern. I became a large concern in the late 80s
when we had machines with resources to dedicate some programs size and CPU
cycles to input checking and error correction....
