This example isn't complete, just to show you how you could do that. ^^
There are more ways, I guess, but I would do it that way. laugh
Hope it helps...

unsure why you're storing trying to store entities and bmaps in variables?

just create what you need as a struct then if you're not happy creating them dynamically or in an array then create them like so:
Code:
#include <acknex.h>
#include <default.c>

typedef struct RND_Q {
	BMAP* bmap;
	char* model;
	int answer;
} RND_Q;
RND_Q* rnd_q; //pointer for array of structs
int int_rndQuestionCount; //stores the number of random questions
int int_rndQuestionSelected;


//panel for displaying the question
PANEL* pnl_question = {
	flags = SHOW;
}

//function for adding question to the pool
void question_add(char* bmp, char* model, int answer){
	
	int i = int_rndQuestionCount;
	int_rndQuestionCount++;
	
	rnd_q = realloc(rnd_q, sizeof(RND_Q) * (int_rndQuestionCount));
	
	rnd_q[i].bmap = bmap_create(bmp);
	rnd_q[i].model = model;
	rnd_q[i].answer = answer;
}

void main(){
	
	wait(1);
	question_add("q01.bmp", "q01.mdl", 1);
	question_add("q02.bmp", "q02.mdl", 4);
	question_add("q03.bmp", "q03.mdl", 2);
	question_add("q04.bmp", "q04.mdl", 1);
	
	random_seed(0);
	
	int_rndQuestionSelected = random(integer(int_rndQuestionCount)); //randomly generates a question
	
	//rnd_q[int_rndQuestionSelected].bmap; //stores the question image
	//rnd_q[int_rndQuestionSelected].model; //stores the mode name
	//rnd_q[int_rndQuestionSelected].answer; //stores the correct answer
	
	//so to display the question in pnl_question use
	pnl_question.bmap = rnd_q[int_rndQuestionSelected].bmap;
}
