Problem with Multi-Dim Array

fogled@mizzou · July 2007

I use very similar code for other functions and it works quite well. But...

DEFINE_CONSTANT
integer ao_ab_z1[3] = {1,25,1} //1=UNIT, 2=DSP, 3=LINE
integer ao_ab_z2[3] = {1,25,2} //1=UNIT, 2=DSP, 3=LINE
integer ao_gr_z1[3] = {2,32,1} //1=UNIT, 2=DSP, 3=LINE
integer ao_gr_z2[3] = {2,32,2} //1=UNIT, 2=DSP, 3=LINE
integer ao_gr_z3[3] = {2,32,3} //1=UNIT, 2=DSP, 3=LINE
integer ao_gr_z4[3] = {2,32,4} //1=UNIT, 2=DSP, 3=LINE
integer ao_c_z1[3] = {3,53,1} //1=UNIT, 2=DSP, 3=LINE
integer ao_c_z2[3] = {3,53,2} //1=UNIT, 2=DSP, 3=LINE
integer ao_de_z1[3] = {3,53,4} //1=UNIT, 2=DSP, 3=LINE
integer ao_de_z2[3] = {3,53,5} //1=UNIT, 2=DSP, 3=LINE

//zone output map
integer aout_blocks[10][3] = { 
ao_ab_z1,
ao_ab_z2,
ao_c_z1,
ao_c_z2,
ao_de_z1,
ao_de_z2,
ao_gr_z1,
ao_gr_z2,
ao_gr_z3,
ao_gr_z4
}

DEFINE_EVENT
button_event[tp_all,btnset_zonedn] //Zone DN
{
    push: {
	send_string debug,"'Zone DSP [1][1,2,3]: ',itoa(aout_blocks[1][1]),',',itoa(aout_blocks[1][2]),',',itoa(aout_blocks[1][3])"
	send_string debug,"'Zone DSP [3][1,2,3]: ',itoa(aout_blocks[3][1]),',',itoa(aout_blocks[3][2]),',',itoa(aout_blocks[3][3])"
	send_string debug,"'Zone DSP [6][1,2,3]: ',itoa(aout_blocks[6][1]),',',itoa(aout_blocks[6][2]),',',itoa(aout_blocks[6][3])"
    }
}

The above code does not return any values for any of the called DSP block row/columns. I can't spot any mistakes that should cause this. Help!

You've found a compiler bug

My first instinct was to reply "you can't assign an integer array" so I tried and you can do so at runtime.

You can also assign an integer array to a member of a multi-dimensional integer array at runtime. News to me!

You can't both declare and assign an integer array in define_variable because the RHS in the assignment has to be a constant.

This compiles but does not work:

define_constant
integer a[3] = {65,66,67}
integer b[3] = {68,69,70}
define_variable
integer c[2][3] = {a,b}

This does not compile:

define_constant
integer a[3] = {65,66,67}
define_variable
integer d[3] = a

This compiles but does not work:

define_constant
integer a[3] = {65,66,67}
integer b[3] = {68,69,70}
integer c[2][3] = {a,b}

Some might say "that's not meant to work" and that's fine by me, but the compiler doesn't say that, which is the bug.

One workaround is to do this:

integer aout_blocks[10][3] = { 
  {1,25,1}, 
  {1,25,2}, 
  {2,32,1}, 
  {2,32,2},
  {2,32,3}, 
  {2,32,4}, 
  {3,53,1}, 
  {3,53,2}, 
  {3,53,4}, 
  {3,53,5}}

...or to assign the elements to the multidimensional array in define_start.

D'oh!

D'oh - I think I've even run into this once before! The rest of the multi-dims I use are assigned with the numbers like:

INTEGER this_array[][] {{1,2,3},{4,5,6},{7,8,9}}

...which as you say really does work.

Thanks!
