Two dimensional array- or something like that? Help please?

Rforbes

Hey all,

I'm getting stumped here. I think this should be simple but it's kicking my.... uh, well... anyway.

Here's my code example

Var

  Byte Temp_0[6]   
  Byte Temp_1[6]
  Byte Temp_2[6]
  Byte Temp_3[6]
  Byte Temp_4[6]
  Byte Temp_5[6]

PUB Main | i

  repeat i from 0 to 6
   
     Temp_0[i]:= i

I'm trying to figure out how to eliminate the need to create Temp_0 thru Temp_5 as I've done above and instead use something like Temp_[6][6] ... I know this doesn't work, but I think it conveys my meaning- to create 6 arrays of 6 arrays.

If that isn't possible, I had at least hoped to be able to access the variables as I have them written by using something like this:

PUB Main|i

  repeat i from 0 to 6
   
     Temp_[i][0]:= i

And of course that doesn't work either.

Am I missing something obvious here?

Thanks in advance,
Robert

Try something like this...

Var

  Byte Temp[36]             ' access via index of 0...35, since arrays are zero-based, right?

PUB Main | i, j

  repeat i from 0 to 5        ' always zero-based
    repeat j from 0 to 5      ' ditto
   
       Temp[i+j*6]:= i           ' puts 0-5 into Temp array [012345012345012345...],

dgately- That helped. Not quite what I'm looking for overall, but definitely sparked some new thoughts. Thanks!

Example of an abstract array of chars. The same concept can be applied to parallel byte arrays.

Mike- thanks man! That's some good stuff. Trying to digest it now.

There's an AppNote for that.

Mike- that appnote was the perfect thing to read. Definitely gave me the information I needed. Much appreciated!
