Preface: New to C

I have a little c program to rearrange some data.  it works fine
on our unix machine (berkeley) but has problems on my amiga.  First
what I am doing.:

I have files of ascii data - integers.

The data is actually a matrix 128 rows by 200 or 300 colum.

The data was originally written as so:

1
2
3
4
5
6
7
8
9

But should be represented as

3 6 9
2 5 8
1 4 7 

After I look at the matrix I then need to put it in row form:

1
4
7
2
5
8
3
6
9


So I just used an array of arrays - scan %d into the array
and printf %d out.  Works fine on unix but if I try it on
my amiga I get very large negative numbers or very large numbers 
mixed in with the data... unless I declare it static but if I do
THAT then I can only have an array size of 128 by 125.

So here is the code:  Instruct me!

#include <stdio.h>
#define ROWS     128
#define COLS     200
 void main ()
{
int i,j, INDATA[COLS][ROWS];

for ( i = 0; i < COLS; i++ ) {
  for (j=0; j < ROWS;j++)
scanf ("%d ",&INDATA[i][j]);    }


printf("%d  %d\n",COLS,ROWS); \* just prints out row and cols *\




for (i =1 ; i < COLS+1; i++) printf("%d\n",i);  \* counts cols *\
for (j = 1 ; j < ROWS+1; j++) printf("%d\n",j);  \* counts rows *\
 

for ( j=0; j < ROWS; j++) {
  for (i = 0; i < COLS ;i++)
printf ("%d \n  ",INDATA[i][j]);     
 
                             }
}



The file using my little array of above

3 3
1
2
3
1
2
3
1
4
7
2
5
8
3
6
9


I wanted something I could use on both my amiga and our unix system...

I just sent the code to a friend with a C compiler (Lattice I
believe) and he compiled it for me.  I probably have a conceptual
here since I am used to thinking (and looking) at this stuff in
rows and columns.

Oh the resulting file then goes into threedplot a program from the
fish disks (the 2d part is now multiplot).  So alternatively if
someones has a 3d plotting program (net type plot) that can use a
matrix of x y and z data PLEASE let me know!

Thanks for any and all comments, advice, instruction, code,
kinder and gentler criticism... but please educate.
