#include "d4all.h"
void main (void) {
CODE4 codeBase;
DATA4 *dataFile;
TAG4 *lastName;
FIELD4 *field;
int rc, j;
code4init(&codeBase); /*Initialize CodeBase*/
dataFile = d4open(&codeBase, "MAILING"); /*Open MAILING.DBF*/
lastName = d4tag(dataFile, "LASTNAME");
d4tagSelect(dataFile, lastName); /*Select the last name index*/
d4top(dataFile); /*Go to top of data file*/
while(!d4eof(dataFile)) { /*While not end of file*/
printf( "\n %4ld ", d4recNo(dataFile)); /*Display the record numbers*/
for (j=1;j<=d4numFields(dataFile);j++) { /*For each field in data file*/
field = d4fieldJ(dataFile, j);
printf(" %s", f4str(field)); /*Show contents of the field*/
}
d4skip(dataFile, 1L); /*Move to next logical record*/
