IBM's Cross System Product (CSP) was an application generator intended to create online systems on IBM's mainframe platforms. Introduced in 1981, [1] CSP consisted of a set of source code generators that allowed developers to interactively define, test, generate, and execute application programs. CSP was composed of two products:
CSP version 3 was released in 1986 with extended functions: [2]
The 1987 SAA announcement cast doubt on IBM's commitment to CSP – it "wasn't silent on CSP; it dismembered it.". [3]
The last version of CSP, version 4.1, went out of support at the end of 2001.
In 1994, IBM released a successor product called VisualGen [4] which incorporated "the ability to develop client/server applications (particularly the addition of Graphical User Interfaces (GUIs) to applications), the ability to access data from non-IBM vendors’ data stores, and the ability to execute application in operating environments beyond the mainframe." In 1996, this product was again renamed to VisualAge Generator. [1] VisualAge Generator was withdrawn from service in 2009 and succeeded by Rational Business Developer. [5]
