RE: 4-bit type

["Brooks R. Robinson" <brooks.robinson@rides.com>]

Greetings,
	You might try something like this...

#include<stdio.h>
#include<stdlib.h>

void main(void)
{
	FILE *fpin;
	char cread;
	char chi;
	char clo;

	if( (fpin = fopen("FILENAME","r")) == NULL){
		printf("Cannot Open File\n");
		exit(1);
	}

	while( (cread = fgetc(fpin)) != EOF){
		clo = cread & 15;
		chi = cread & 240;

		/* Do your thing here */
	}

	flclose(fpin);
}

	You could read the 4-bit values into an array, or use them two at a time.

Brooks

	P.S. No, I didn't test this code, and I am not 100% sure about the bit
twiddling.
