PICBASIC-L Problem with arrays

[Peter Meyer]

If I declare an array (i.e. test var byte[10]) and other byte or bit
variables, some of the byte and bit variables change their values when I
write to the array. As soon as I declare the variables as word it works just
fine...
Any ideas??

Thanks
Peter

Make sure you read the info in the manual about the numbering in arrays.

test var byte[10] will declare a 10 byte array

test[0] is the first byte in that array and test[9] is the last.

Actually I beleive a var byte[10] is an eleven byte array elements 0 through
10.

Belief doesn't hack it, pal. If, rather than believing, you will read the
manual, you will see that var byte[10] is a 10 byte array, numbered 0 to 9.
Try counting your toes, starting with zero.

Yikes.

I'm not even using the whole array. I also tried to alter the size ([8] ,
[12] , [11] ...) - still the same problem.
What really makes me nervous is that the whole thing works perfect when I
declare all the other variables as words!
The program is about 4k words in size and I'm using 18 word variables and
two arrays (one has 10 bytes the other 16 bytes).

Peter,

Are you sure that you are writing a byte to the array?. If you have another
variable defined as a word, and the value in this variable is 255 or less,
you may think that you could safely write this value to the byte array. This
is not the case, the value will still need to be stored in a word array.

I came across this by mistake a while ago.

We could stop half the posts on here if we would read the manual.
I stand corrected and appoligize.
I hope your Highness can forgive!

Maybe I am wrong here and I hope I am and someone points it out but most of
the printed stuff seems to be in assembler (or whatever it is called) and
the likes of me might as well row up a crocodile infested Queensland river
in a barbed wire canoe without a paddle and would find that easier than
trying to learn assembler..
