What have I do wrong? I get only a lot of errors when I try to run this:

+ Code Snippet

#include "DarkGDK.h"

float lol[4][3];
for(int a = 0; a < 4; a++)
{
	lol[a][0] = 1;
	lol[a][1] = 2;
	lol[a][2] = 3;
}

void DarkGDK ( void )
{
	dbSyncOn   ( );
	dbSyncRate ( 60 );

	while ( LoopGDK ( ) )
	{
		printlol();
		dbSync ( );
	}
	return;
}

void printlol ( void )
{
	for (int b = 0; b < 4; b++)
	{
		lol[b][0] = b;
		lol[b][1] = b * 2;
		lol[b][2] = b * 3;

		dbPrint(dbStr(lol[b][0]));
		dbPrint(dbStr(lol[b][1]));
		dbPrint(dbStr(lol[b][2]));
	}
}

1. You have code outside of a function. This isn't allowed.
2. You're trying to call a function without first specifying its prototype. You can fix this by either placing that function above the other, or by specifying a prototype above the other function:

+ Code Snippet

void printlol(void);

3. You're passing a float to dbPrint, I'm not sure if this is allowed. If this is the case, keep a buffer handy to output data to, and pass this to dbPrint:

+ Code Snippet

char buffer[256];
sprintf(buffer, "%f", lol[b][0]);
dbPrint(buffer);

I'd take that buffer bit even further - if you can - I personally made a 1k buffer like that - and I put it in a NAMESPACE so I can access it from anywhere in my program. Makes for a quick-n-dirty text buffer for EXACTLY the kind of thing Benjamin showed ya.

dbStr() can convert float to string, I know it.

And how I do if I whant a global array, but I can't use code outside a function?
