At I. P. Sharp Associates in Toronto, Arthur Whitney and Kenneth Iverson put the Airline Guide online. Arthur did all of the coding. In the twenty years since then, this has run for 24 hours a day and 365 days a year. Whitney also wrote an APL system for Hewlett-Packard Australia. At Morgan Stanley, he wrote A+. This is a descendant of APL and a predecessor of K (K Language). Arthur Whitney developed A+ in the late '80s in response to employer Morgan Stanley's need to move their APL applications from mainframes to Sun workstations. He later left Morgan Stanley and wrote K.
