C++ Example and Function List
C++ Example:
// List the MAILING.DBF data file ordered alphabetically by last name.
#include "d4all.hpp"
void main(void) {
Code4 codeBase; // Initialize CodeBase
Data4 mailing(codeBase, "MAILING"); // Open MAILING.DBF
Tag4 lastName(mailing, "LAST"); // Define an index tag object
mailing.select(lastName); // Select Last Name ordering
mailing.top(); // Go to top of mailing file
while(! mailing.eof()) {
cout << "\n" << mailing.recNo() << " "; // Display the record number
// For each field in the mailing file.
for (int j = 1; j <= mailing.numFields(); j++) {
Field4 field(mailing, j);
cout << field.str() << " "; // Display each field’s contents
}
mailing.skip(); // Skip to the next record
}
mailing.close();
