What the Toolset Generates

‍

‍Once compiled and linked, the resulting executable will run seamlessly with Oracle, eliminating dependency on Pro*Fortran while maintaining compatibility with existing applications.

Before and After - Code Example

Fortran

! Original Rdb SQLMOD in Fortran
EXEC SQL CONNECT :user IDENTIFIED BY :password USING :dbname;

‍

Fortran

! After conversion with Sector7 Toolset
CALL connect_to_database(user, password, dbname)

‍

C

/* Generated Pro*C procedure */
void connect_to_database(char *user, char *password, char *dbname) {
    EXEC SQL CONNECT :user IDENTIFIED BY :password USING :dbname;
}

‍

This illustrates how embedded SQL is extracted and converted into standalone, reusable procedures, making the application fully compatible with modern Oracle or PostgreSQL environments.

Result:

Oracle - and PostgreSQL - ready applications that maintain operational continuity and are built for the future.
