REXX is the programming language designed for people, not machines. It swept IBM when it was first distributed on IBM's internal network by its creator. With heavy use by a lively networking community, it has evolved to meet the needs of its users. In 1987, IBM acknowledge its success and adopted it as one of the cross-system SAA (Systems Application Architecture) languages. Now, REXX has spread outside IBM, on both mainframes and micros. Today, more than six million people have REXX on their systems.
