I'm not sure why I still include this in my resume. The X/L DBMS was developed for the Call/370 time sharing system. Since computer time sharing is dead so is Call/370 and the X/L DBMS. My employer at the time was Control Data Corporation that is also gone. The major application was for HCFA located on Security Blvd in Baltimore. I quit CDC before this went live. Things didn't look good for the business or the technology so after ten years at CDC I left looking for something going somewhere.
